A Boomer just asked whether she could send a second smaller piece of fabric to be used as an accent piece. The answer is yes. Try to keep the piece to 8 1/2 inches square or less to keep us from going right back to the squashing issue of too much fabric in an envelope.
Also, a reminder that generally Boomers keep the remnants from the F8s and accent fabric they receive unless there is a specific request by the owner to return them. Not everyone keeps them but it's been customary to do so throughout the Booms.
