So After you get your material you may want to wash the fabric. It's up to you and if you do wash in cool water with like colors. If you are afraid of the edges fraying use pinking sheers to trim them. Otherwise you will need to iron your fabric. You can skip the chenille but Always iron your cotton fabrics.
First cutting the chenille
Now a yard of fabric should be 36inches wide along the selvage. Mine was not. So I trimmed my edge down so it was about 35 inches instead.
What it should look like Pretty square to be honestWhat mine looked like...not exactly square so I trimmed the edge
Next you want to trim the Selvage off. Its a little hard to pick it out on chenille but its there I promise.
Next you want to Measure up 37 inches and use your marking tool to make a straight line across and then cut
you should now have a rectangle that is 37x35inches.
Now chenille is very stretch so don't expect perfection because in the end you really wont be able to tell is off by a 1/4 inch.
Now for the other piece of fabric
First remove the Selvage
The easiest way to do this is to lay the fabric flat then lay the 37x35 inch cut chenille over it and then cut off the excess.
If you are piecing you should keep in mind that you want your end product to be 37x35inches.
Next up making the piping edge!
