Lay the two pieces down with the edges overlapping a couple inches . Cut through both edges at once in a gentle curve and get rid of the little edge pieces that are created. Then either loosely hand sew the curved edges that are butted up to each other or iron a strip of fusible interfacing over the seam to connect the two big pieces. I hope this is clear enough without any pictures. Karen
Karen and gang,
I sometimes sew the gentle curve of batting with a large zig-zag stitch especially for placemats that get washed a lot. athis guarantees that the batting will not shift a bit...
I butt my pieces together, but I use what is called a multiple zigzag stitch or tricot stitch (I have a Janome 6500, this is mode 1, stitch 9). It looks like a regular zigzag, but each zig is made of 2 or 3 short stitches. This keeps the batting from puckering.
I recently heard of something I will try next time. Instead of sewing the pieces together use a lightweight fusible interfacing! Overlap the two pieces and cut the joining line; remove the scrap pieces and fuse the interfacing over the join! I wouldn't try it on a polyester batting, but I'm definitely going to try it on cotton!
