I have 16 placemats tops to finish for a church project that will occur around Christmas. I was talked into birthing them so I won't have a truckload of binding to be hand stitched. After many days of contemplating, I thought I had a solid plan. I spray basted the batting to the front being 1/4" shorter so there would be no doubling of batting in the seam. I used the small tube of Elmer's Washable School pen very sparely so that the batting would stay in place. But NOW, I am not sure how to press the seam open and then press it flat in place so that the edges of the placemat will be where they should be. Thank you for helping this old dog learn a new trick.
