I'm with you Marnie! I think sewing for charity is a great way to purge your stash of fabrics that are not matching up with your current taste, or if you have so much extra that you know you will never use it up in your life time. Rather than taking up space it can help someone in need. Sharing the love. I just suggest pillowcases b/c they don't take up much time and they don't require a whole lot of fabric, or a lot of coordination of colors, etc.
Please spread the word on the pillowcase challenge if you can. It may help some folks to reach out to local organizations and extend to baby quilts for newborns, layette covers for premies, etc.
Happy stitching everyone!
