When you can recognize all the marks on your pattern, trim off the edges and pin it together. Have your leader check it for fit. She will help you make any alterations that are necessary.
Straighten your fabric
Study your fabric. You will find there are threads running lengthwise (warp threads) with other threads woven in and out of these (crosswise or filling threads). Each of these threads should be straight, not curved or slanted. If the end of the fabric has not been torn, pull one thread near the end that will go all the way across the fabric. Cut along this line.
Now if the ends of the fabric are not even, have your leader or mother help you straighten the cloth by pulling on the bias, as is being done in the picture.
When the cloth is straight, pin the edges together. Now pin the pattern to your cloth.
Crease-resistant fabric cannot be straightened.
