I love sketch challenges - it's so hard for me to start a card most of the time and having a layout in front of me helps me tons. So I do hope I'm not committing some kind of faux pas when I mix and match my sketches and products! I don't have any My Favorite Things products but I just kept favoriting one of their designers on SCS (Inge) and discovered their sketch challenge that way.
