this very easy Tunisian crochet pattern, I made this pair of slippers in 2 days. I did need to make some tweaks to the pattern, but they were minor tweaks. The pattern said to make them the length of your foot plus an inch, but that made them massive. They stretch, so the length of your foot is plenty. Mine are 21 rows long plus the decrease row (size 9 shoe). The other tweak I did was that I used a size J hook and did a slip stitch around the whole thing at the end (after the single crochet round with a size K hook). The yarn that I used was perfect, and very soft: Cascade Yarns Pacific Chunky Multi. I used about 96 yards of the 120 yard skein. The cool buttons I bought at Aunt Margaret's Yarn & Gift Shop (as well as the yarn).
The only real issue that I ran into with these slippers is that I had to mail order the size N Tunisian crochet hook. No one local sells anything larger than a K.
