Yarn: Knit Picks Suri Dream (plus some worsted merino on his belly area for contrast)
Hook: F (3.75mm)
This technique is called brushed crochet. You crochet your item, and then literally brush the fur out. The pattern calls for a slicker brush (which you can find at pet stores.) Instead, I used my new handcarders as my brush - and they worked great. Surprisingly, pretty much any yarn will work for this. The suri alpaca worked extremely well to give a nice long coat to the doggie, but the merino yarn I used on his belly brushed out quite nicely as well, although not as long. I ended up with some holey spots (I really needed to crochet this much more tightly than I did), but they were easily covered over with some creative darning and vigorous brushing. :-)
Overall, a very fun and quick project! And now I have a cute doggie of my own, who doesn't need walked and fed! Win, win situation for me!
