Press the seam flat, pressing the lining to the inside, now topstitch. Now you will crossover the tops, remember that one is to the left and one is to the right. Now stitch them in the seam allowance to hold together.
Now put your soles together, follow the directions for this in your pattern. You have 3 layers, pellon fusible fleece, lining and slipper gripper.
Now you will attach the soles to the tops. Make sure to line up the right top with the right sole and the left top with the left sole.
- Now take the sole and place it on top of the slipper. The slipper gripper will be touching the pieced part of your slippers. Pin in place, starting by matching the tabs and the center fronts and center backs, then pin all the way around. If you wish you could baste this seam first. Now stitch all the way around the slippers, if you like you can stitch again with a small zig zag stitch and cut away any excess to clean up the seam.
- After you have finished stitching this seam, turn it right side out. If the slipper is too wide for your foot, you can take it in on the sides, not the toe and heel, this will change the size. Now finish your insoles according to the directions in the pattern, then add the insoles.
