I followed the tutorial for these slippers on the planner and procrastinator blog and it was fantastic! They have a link to the pattern at the top of the page, but I hardly used it, I just followed their clear step by step photos. I decided not to make the flower for the front, but kept them plain instead.
One word of warning about sizes; I'm a 6 and the girl making them was a 6.5 but I made them originally to the exact pattern specifications and they were far too big, I had to take about 3 rows off. I don't know if this is because my tension is looser. Just use your judgement.
