An O is easy to make. Start with a small background square, and sew your letter fabric all around on all sides.Sewing it together is easy. It's trimming it that makes it so much fun. Where do you want that hole in the O to be?
O... the possibilities...And then, of course, you can tinker with the shape of the O...And remember, letters work together to form WORDS. This DOG is from The Brown Fox quilt. Doesn't the low hole in the O help make the word look slow and lazy? Here we've got two O's next to each other. Two identical O's side by side wouldn't have been particularly interesting.
So have some fun. Make your O with LOTS of extra letter fabric so you can trim it down later.
