I would try sewing a stay stitch almost on the seam line of the upper and then clip the seam allowance at about 1/4 to 1/2 inch intervals up to the stitching.

I think it would be easier to line up the uppers and the soles if you do that.

I didn't think about that ... I'll try it. The challenge will be to keep it from bunching up, so I can still walk in the slippers. Thanks.

Adorable! I might just have to try them for next Christmas. :o)

I just googled them and found a free pattern here!

really cute slippers.

Love the pattern. What wonderful Christmas presents.

Where is the problem you are having? I know putting the sole to the top takes a lot of pinning and easing in usually on slippers.
