thanks everybody for the nice comments. The slippers are really easy. here is the pattern that I used:
I cut 4 of each piece
the top of the foot is on the left. For the bottom part of the foot, you just trace around your foot and then add 1/2" for a seam allowance. The top of the foot I just had to play around with to make it fit. first i sewed the parts that were close to the ankle right sides together and turned it right side out so that it would have a nice finish. as far as fitting it around the back, i just pinned the toe area and then worked my way back from there and overlapped the parts that i had left over. For my slippers, i wanted them to be finished on the inside too, so i used two pieces of the sole fabric wrong sides together when i sewed the sole to the top of the slipper. the strap is just two rectangles sewed together and then i put a snap on them. my explaination seems complicated so I hope all this makes sense to everyone.
