I posted pictures of four BOMs, the two that I didn't get labeled are Henryetta's Whiskers and the other is My Tweets.
To answer your questions: I only do machine applique. I usually buttonhole stitch around each piece. The folk art types will be in black thread and the others will be in thread to match the pieces or transparent thread.
I am using fabrics from my scrap basket as much as possible or from my stash. I may need to buy fabrics for borders.
All these BOMs finish at different times.
I have four more started but couldn't get the pictures posted. Will try again later.
