Big congrats on your three and a half days! I crochet, too, and found a little pattern for a holder online. I got started on it, and realized I didn't really need a holder, lol. I have one - it's my hand.

Kidding, kind of. But I do tend to carry my ego around from room to room. I don't work and am retired, so it makes it easy to do. Again, I'm proud of you!
PS Your holder is super cute. Did you have a pattern or just wing it?
