What a difference knowing about fabric grain has made to my finished quilts. If you have had difficulty getting your quilt to lie flat once completed, then this could be the solution to your problem.
When looking at the grain of your fabric we are talking about the direction that the threads run. From a quilters perspective, we talk about a piece of fabric having 3 types of grain:
Step 3: Rotary Cutting your fabric into strips is a lot easier when cut along the lengthwise grain (parallel to the salvage). Using your large rotary cutter, cut your strips to match the template widths you are using. When using Marti Michell's templates it is very important to place them on the lengthwise grain as marked on the template.
Grain of Fabric Tip When cutting your borders & bindings it is best to cut them on the lengthwise grain. This does use more fabric but the end result is well worth the cost.
There are of course times when it is not essential to use the grain of the fabric. One of these is when paper piecing blocks. I am currently making my DJ quilt which involves quite a bit of this technique. I have fussy cut fabric to suit and totally ignored the grain. Fortunately the paper offers stability. The other time is when cutting out your applique pieces.
If you don't want to or can't cut your fabric on the appropriate grain then using a bit of spray starch will help stabilise your fabric while you sew it into your quilt. Often by the time the quilt is finished the starch has all been removed. Of course a quick wash will remove any residual starch should you feel the need to do this.
