These are beautiful - I love the heart. Crazy is one of my evening handwork projects too - I've only done two blocks so far and have no idea what it will end up as but I love all the ribbons, embroidery and little doodads you can include! Plus, it widens out the shopping obsession from fabric and tools! I scrounged around the house for stuff as well - buttons, beads from a broken bracelet of my daughter's, odd earings, one of DH's silk ties (I asked him first!). I also am using some non cottons, my little girl's outgrown velvet dress, some organza type stuff etc. Anything like that, I iron on to interfacing to stabilise it.
Do you piece your blocks by hand or machine? I did a couple a while ago which are 9" squares hand pieced onto a muslin foundation but found them too big to work on comfortably so they are now pinned up in my sewing room - maybe I'll make them into cushions or something. My new project is with 6" squares and I machine pieced them, no foundation. It's fun isn't it? I must pick mine up again, haven't done any since Christmas becasue I'm trying to finish a hand quilting project. Maybe I'll do some this evening! :-D
