What Not To Crochet (viewer beware before clicking that link, it's not always pretty, it's sometimes scary, and it's often not child friendly...sure is funny though), I give you the crocheted curler. Am I crazy? Perhaps. However, when I put these in my hair at night instead of the old sponge rollers, I actually get to sleep pain free. Frankly, I think pain free nights are totally worth the few hours and scrap yarn used to make a set of these. :D I've considered buying the soft pillow rollers before, but to get enough for my hair would cost more than I really care to invest. I've tried rags, but I have a hard time rolling them up and tying them. These were quick, easy, and free (since I used leftover yarn) to make. They were inspired by these knitted ones that I found while looking for ways to use up yarn. I tried to follow the knitting pattern, but knitting 6 little stitches over a set of DPNs is a little beyond my beginner knitting skills. I quickly decided to come up with my own crochet pattern and whip some up that way instead. I don't have a strict pattern for them, but the basic idea is as follows:
I used a US size F hook
Work 6 sc in a magic loop (more if you want a thicker curler), do not join
Sc in each sc around until you reach about 3.5 inches
6 Foundation single crochets, join end to the end of the curler body to make a loop. Finish off.
I have found that the loop stretches out as you use it, so make the loop smaller than you think you will need it to be. I made mine with various amounts of single crochets, and in the end I think the ones with fewer (around 6) worked out better than the ones I did with more. You could also stuff your curlers before you sc3tog if you want them a little firmer. I chose to leave mine hollow inside, and they work fine. I think that if you decide to make yours bigger, it would probably be a good idea to stuff them. Mine are fairly thin, so they hold up well without anything in them.
I cannot set my hair wet because it will never dry if I do. I did try these out with a wet set, but, as usual, a good 10 hours later they were still wet when I went to unroll them. This happens with sponge rollers as well for me. I can't say how they will work on other people. If your hair dries easily overnight in rollers, these may as well. For me, I just mist a little diluted Lottabody setting lotion on each chunk of dry hair before rolling it up.
