be careful of your dining room table with those pins. my girlfriend ruined hers but her Hubby refinished it for her. When i pinned i used a folding table. it has a one inch depth so i used the white clips Eleanor Burns sells on her site, Quilt In A Day. before that i used a folding picnic table and used binding clips. I would clip the backing in place, add the batting, smooth it in place and reclip. then add the top, reclip. then pin, pin, pin. good luck.
