I have put the pattern up as a .pdf over at Knit Natters:
You will find this pattern much easier to follow if you watch the videos:

A few notes and comments:
1. Most people don't know sock sizes - at least I don't. What I decided to do was chart the slippers following the sizes at the Yarn Council's standards web pages. If you measure around the largest part of the foot (the ball) and you measure the length of the foot, you can pick your size that way.
2. The gauge of the slippers for the pattern is 4-1/2 stitches and 6-1/2 rows equals 1". In metric measurements, 18 stitches and 26 rows equals 10 centimeters. I got this with a light worsted weight yarn and Tension 4 on my Brother 270. Measure gauge with the yarn you are using for the outer slipper, not the lining. The lining is made on a tighter tension so it'll fit inside the outer slipper.
3. Yarn - For this project you can use up scraps of worsted weight yarn. Yes, American 4-ply acrylic yarn will work, but the better the yarn is that you use, the better your results will be. The slipper shown is less than 50 grams of each color. It's a woman's size 7-9 (sock size).
