I actually folded 24 cranes last weekend, but didn't take the time to create a post.
And instead of devoting the entire day yesterday to homework, I watched movies and folded cranes. After finishing 16 and threading a second string of 40, I decided that I'd fold another 40 so that I'd have 3 strings completed altogether. By the time I was done, I'd folded a total of 64 cranes over a period of 5-6 hours and was definitely tired of folding for the day.
The bright side is, the 3 strings of cranes look nice hanging in the corner of my bedroom.
By the time I'm finished with 1000 cranes, I'll have another 22 strings, which will be quite voluminous. But there's room for them, so it's not a problem.
