Debbie over at Homemaking Dreams made a quilt from her son's jeans and other clothing items. Do click on the picture(on her blog) and take a closer look, it's so nicely done.
She has linked the free pattern and tutorial. The pattern is called Gentleman's Quarters. My grandmother had handmade quilts on all the guest beds at her home, and they were very similar to this pattern. It brings back pleasant memories seeing this particular pattern.
