I stopped at 26 inches across because I'm anxious to try making one with t-shirts to see which method I prefer. This one took approximately 2 Queen sheets and two twin sheets. I used the ripping method rather than cutting the strips with scissors.
I gave you two links in my April 18th post which is where I got most of my information. I also Googled and read different tutorials. I cut my strips about 1.5 inches wide, and as I was crocheting, I'd fold the strips in half so that the right side was showing. It would be best if you just didn't use sheets that are only printed on one side of the material. Also, I wouldn't roll them into a ball next time, but instead I would just fold it together more like a hank of yarn so that it doesn't wad up and get all wrinkly. It's a pain in the ass to pull all the threads off as you cut your sheets, but it sure made things a lot easier once you're crocheting.
No, my hands didn't hurt, but my shoulders did (first from ripping sheets and then from crocheting), and my forearms were a little sore too. But neither was a big deal. I could just tell I'd been doing something I don't normally do. I found that sitting at my desk to crochet this was easiest for me.
I'm not sure what size my hook is because it's not written on it anywhere and I bought it at least 15 years ago, but it's either a P or a Q.
You can see how big it is above compared to a ball point pen.
I got some t-shirts at the thrift store this morning to use for crocheting a rug. They are in the wash now, and I'll begin as soon as they are dry. See the YouTube Video HERE for instructions on cutting and making your t-shirt yarn. You can Google "making a rug out of t-shirts" and find different ways to connect your t-shirts after you have cut and stretched them.
Somehow I think I'm going to like using the t-shirts better than the sheets, but we shall see.
