How to cut fabric straight

Cutting fabric straight is really important and can’t be stressed enough. A bad initial cut can result in twisted seams, or seams of different length on two pieces that are supposed to match, or a deformed/uneven after the garment was finished. It is surprising, but indeed a wrong initial cut can actually cause all these issues. Just to make it clear, the question here is how to cut large pieces of fabric straight.

It seems to be a simple task, cutting fabric straight, but in reality, there is more to it than is obvious at a first glance. Below are some helpful tips on how to cut material straight.

Fabric cut in the store is not always cut straight. Sometimes the bevel happens to be 5-10 cm or even more. So before you can use your fabric you need to find out how to get a straight edge on fabric. Proper preparation of the fabric is vital in sewing.

What will happen if you make for example curtains from a fabric without straightening its edges? If you hang such curtains all this unevenness will immediately be visible.

It is very important to straighten fabric edges for any sewing projects BEFORE cutting pattern pieces from it.

In the end, how do you cut fabric straight ? There are quite a few methods to square the fabric before cutting the pieces. But before measuring and cutting you will need to do some preparing.

1. Find out if your fabric is woven, knitted, or non-woven

Differences between the three types of fabric result from how the manufacturers produce them.

fabric is made of many threads that run vertically and horizontally in a crisscross pattern. fabrics are usually not stretchy and keep their shape unless the threads themselves are stretch, for example, some fabrics may have elastane threads, then they become a little stretchy.

fabric made of one continuous thread being looped back and forth. Manufacturers make fabric using a series of needles to loop and interlock fibers. Knits stretch vertically and horizontally, and the amount of stretch differs.

Non- fabrics are bonded together mechanically, thermally, or chemically. They are flat, porous sheets that are made directly from separate fibers or from molten plastic or plastic film.

All fabrics have selvages – self-finished edges of fabric that keep it from unraveling and fraying.

When you buy a piece of fabric from a store you will have a along both sides of your fabric. And generally, edges are always straight.

It is important to find the for your fabric. is the direction of threads running parallel to selvages. In different words, is the lengthwise direction of the piece of the fabric.

2. If your fabric is woven iron it flat first

Usually, fabric coming from fabric stores is folded in half lengthwise matching the selvages . Get rid of the folds and wrinkles. Generally, you don’t need to iron knitted or non- fabric.

3. Prepare a flat hard big work surface

A big square table is the best . Don’t cut fabric on a bed or a carpeted floor. If using a dining table extend the table to its maximum length. If all else fails, use the floor. Keep the table uncluttered. Put all the fabric edges on the table and make sure that nothing is hanging over the table and pulling the fabric down.

4. Prepare a pair of good sewing scissors

They have to be sharp and comfortable for your hand. Or you can use a special cutting tool — a rotary cutter.

How to cut fabric straight

Ok, now you are ready to learn different methods of cutting fabric perfectly straight.

1. This first method is my favorite and to me, it’s the best way to cut fabric straight. It can be used for many fabrics. It is very simple, very precise and requires only attention and patience.

Find the unfinished edge of a fabric .

Pick out a single thread on the frayed edge and carefully pull it. As you pull the fabric will gather a little. Straighten the fabric and pull the thread out completely.

You will notice that it left a visible gap line. Gently cut the fabric along this “path”.

How to cut fabric straight

As you pull the thread it can break before you reach the . Not a problem. Cut along the path till you get to the place where your thread snapped. After that choose another thread in the same line and repeat the process until you cut to the .

Your cut will be perfectly straight.

Cut with one hand holding the fabric and the other hand holding the scissors. Don’t lift the fabric from the table.

Perhaps, you should read my other popular sewing tutorials if you are interested in sewing.

2. The first method is not good for knitted fabric. So here is the second method you can use for knits. By the way, it is good also for some fabric and for non-.

How to cut fabric straight

So line up one edge of the fabric with one of the edges of the table. Put some weights on the fabric or fix it with the painter’s tape so the fabric doesn’t move. And now look how the cut edge of the fabric aligns with the other edge of the table perpendicular to the first one. You will see that fabric goes slightly outward or inward of the table edge. Move the fabric so that nothing is going inward. Make marks on the fabric, draw a line and cut.

To cut it straight is very easy. You can take a ruler with a 90-degree angle . Lay the ruler on the fabric so that one its side lines up with the edge and the other side crosses the fabric at a 90-degree angle. Hold the ruler firmly and draw a line with a marker. This line will be perpendicular to the and perfectly straight.

I have to mention here that knits also have a but it’s different than on fabric.

The on thick knits can actually be seen. The little vertical rib lines in the shape of v- stitches on the right side make the , like on a knitted garment. So if you want to cut fabric straight you have to cut along the .

In the image below you can see raw silk fabric with grainlines easily visible. Sometimes I trace a line of stitches along the just to be sure that I cut fabric straight.Save

But most of my knits are very thin because I like to sew with gorgeous silk jersey fabric and the grainlines can’t be seen there. In this case I just find the with my ruler, because the is parallel to the line.

It’s really important to cut knits strait , otherwise you can end up with twisted side seams and completely distorted garment .

When you have three straight lines on the fabric — the one you just cut and the lines – you can measure from these straight edges whatever size square or rectangle you need. You can fold the fabric lengthwise lining up all the straight edges. And now measure with a ruler the amount you need for your project and cut.

3. The third method is good if you have a special cutting mat. Put fabric flat on the table. Measure the distance between selvages and divide it in half. Make a few marks on the fabric parallel to selvages and draw a line with a long ruler.

Fold the fabric along this line, to .

Put the folded fabric on the cutting board with grid lines on it, align the folded edge with a line on the board, make a straight line perpendicular to the folded edge and cut the fabric.

4. The fourth method is very precise also: it’s ripping the fabric.

But it does not work for all fabrics. Only some fabrics can be ripped. As for me, I rip many lightweight fabrics – silk, cotton, even thin wool. This method is applicable only to natural fabrics of good quality. Don’t rip fabric with elastane in it. Never rip fabric along grainlines. It’s only good for direction on crosslines going perpendicular to selvages. The ripped fabric edge can become noticeably more loose or wavy. But it will be perfectly straight cut though. So, if you don’t want this ripped edge which can look a little distressed – measure about 5 cm from that edge, draw a straight line parallel to the ripped edge and cut with scissors.

This method is especially good when you want to use fabric previously cut for some other project where you can’t even find edges.

How to rip the fabric? Snip fabric with scissors about 3 cm from the edge, then pull the fabric apart.

Have in mind that ripping very close to the edge of the fabric may not be successful.

5. The fifth method is not really very useful because with it you can’t cut close to the cut edges of the fabric. So it is good only if you want to have a straight cut somewhere in the middle of the fabric piece.

Fold the fabric in half in width and carefully align selvages. Smooth the fabric with your hands, so there are no wrinkles anywhere. And the folded line will be straight.

6. If there is a certain pattern or a certain texture on the fabric that will help you to cut straight, it means that you are lucky. So, if you want a straight cut on the fabric with stripes, plaids or some prints you can follow the designs on the fabric.

7. There is a special tool for cutting fabric straight. It’s called Laser Guided Fabric Scissors. But according to the instructions, you suppose to draw a line on the back of the item to be cut and line up the laser with that line as you are cutting.

How to cut fabric straight

So I don’t see a point to use this laser if first I have to draw the line anyway. If I draw the line I cut along the line with regular sewing scissors. Moreover, it is hard to keep the scissors from shifting with the movement of my hand making the laser point in a different direction. So for me, these scissors are really worthless.

8. When you need to cut squares or rectangles and already have 3 straight edges, if you are in a hurry and don’t want to mark cut lines with a ruler you can follow this technique: make a short cut perpendicular to the . Now fold it up and keep edges even along the side that you already cut. Now cut along the folded over fabric. Repeat the process few more times.

This method is mostly good for a sturdy cotton fabric.

I use these methods to cut fabric perfectly straight. I hope this information was useful to you.

Sometimes fabric can be stretched off-grain in manufacturing. If you followed the above steps trying to cut fabric straight but you still see that the ends are not even and one end looks shorter than the other than you have a bigger problem and have to square up the fabric before using it. But I don’t think it happens very often. I am sewing for 30 years already and had this problem only 2 or 3 times.
