Not really sure..One day the notion just hit me..What is so funny is I hated to sew growing up..Still can not read clothes patterns, tried to sew a few outfits in the last year and they were enough to make anyone shutter :-D ..Than it hit me..a quilt..Went looking to see what would be the easiest one for me to do and found out how to do a string quilt..I started it, and now I can not put it down..I love it...
