Quilts for Kids is a great idea. Ask them for a kit and you will then know just how big, style, etc. they need. The kits they sent me were youg boy oriented. So I am now working up designs for girls...they get sick, too.Young teen boys like sports, hunting, fishing,... maybe not so loud colors. These quilts are small 45x55 or so. Good way to try out a new design/pattern. I just got a big load of fabric at a Walmart that's eliminating fabric, for 1/2 price. Also, the 10 yd roll of batting at JoAnns was on sale at 1/2 off and will do about 8 of the quilts for kids.
Also good size quilt to try free motion quilting or whatever style on your home machine. Hobo quilt designs and some Amish designs would work for young teen boys. You can find these patterns FREE on the web. Floridacabinfever.com had a bom pattern for Amish quilt, lap size. Download pattern for free. Great pattern for a beginner. Quick and easy.
