I've tried to explain how I did this, but it's important to first follow the instructions of the other instructable to get your pattern.
Step 1: Step 1
If necessary zigzag the fabric.
Pin the inner and outer fabric as shown and sew it together.
As shown in the second picture I've added a extra wool filling in the sole and attached it while sewing the inner piece together.
Step 2: Step 2
Step 3: Step 3
Step 4: Step 4
(this is why you needed step 3 so the inner piece stays in place)
I've used fleece on the inner and the hem piece of jeans for the outer so no problems with creating a new hem.
After you've put the toe pieces together I hand-sewed the heel piece inside the toe piece.
(like in the instrucable of the pattern)
Step 5: Finished Product for the Men
Step 6: Finished Product for Women
I used a sleeve of a wool sweater for the hem piece of the toe part of the inner pattern.
That's why I had to do it a bit different with step 1 2 and 4.
At step 1 I left the overlap on the heel piece loose. I also left 1 cm of the toe piece loose (to flip back over the jeans toe piece)
At step 2 I did sew the heel pieces together but I stitched the overlap to so I had to turn that.
At step 4 I flipped the 1 cm extra of the wool piece that I left loose over the jeans toe piece and stitched it together.
Ánd after that just hand stitched the heel piece inside the toe piece while I also attached the pink ribbon.
