OKsewglad, in my opinion, is the "mini" goddess. She is amazing and these are no less stunning pieces. She is the reason I started doing mini's. Just love her stuff and admire her skills.
Judith....I use a creative grid and square my HST's, too. Just have to remember to cut pieces larger than pattern calls for so you have enough to trim away. But, 600 plus would do my head in. Lol! adorable postcard and perfectly pieced, which does not surprise me.
Anael...rockin pic, girl..... Did you ever consider printing some of your favorites on fabric and making a quilt? Some are so frameable they are that beautiful...
So, off to paint some more....
