Some popular trends are Anita's Arrowhead, Twister, rope bowls, disappearing 9 patch, and Bonnie Hunter's Scrappy Trips Around the World. How about Featherweight cleaning? Using machine feet and attachments? The Disappearing 9P
can also be used to make I Spy blocks that are automatically sashed for quilting when the 9P is made with the novelty blocks in a certain orientation. I have it bookmarked somewhere if it's needed.
