Learn something new everyday even when it's sitting right in front of you. I have a pressing clapper I got at a yard sale a few years ago for a dollar. I use it when making clothes and never thought of using it for quilt block seams. Duh!!! Thank-you for the new sewing tip. I took a small wood dowel and sharpened the end in a pencil sharpner and use that for pushing/holding seams as I sew.
