I decided yesterday to try making him a Valentine's Day bow tie, with two hearts making up the bow part of the bow tie.
I started with a red worsted weight yarn (just a small ball left over from another project) and a size F crochet hook.
I used this amigurumi pattern  to make two stuffed hearts. They're adorable by themselves. The first one was a bit of a challenge, but the second one was easy peasy. That's normal for me.
I originally thought I'd use a tiny heart as the middle section of the bow tie, and made one using this pattern.  But when it came time to put together the bow, it just looked messy.
Instead, I single-crocheted a small strip for the middle using the same yarn and hook. It was three single crochet stitches wide and about eight rows tall.
I also single-crocheted the tie part of the bow tie, with a strip about five single-crochets wide. I'm not sure how long it was. I just made it long enough to fit - without being too tight - around Milou's neck.
To assemble the bow tie, I tied the pointy ends of the heart together, using a needle threaded with the same red yarn. I then sewed the smaller strip to the middle, and then attached the middle of the bow to one end of the tie strip.
I cut a small piece of velcro (the kind with the sticky back) and stuck the scratchy side on the back of the bow. I stuck the soft side to the other end of the tie after making sure it wasn't twisted.
I don't like using velcro with crochet because it can make the yarn all fuzzy, but I wanted to use a closure that would come unstuck if Milou got caught on something. I figured putting the rough side beneath the actual bow would keep that part from getting damaged.
The result is adorable. Doesn't Milou look like a cute litle Valentine?
