Hey Laney, Thanks for stopping by my blog! To answer your question, I would say the sweatshirt took about 1 hour total, but you have to do it in phases, since you're waiting for the bleach to dry before you can sew on a letter. Anyhow, good luck! It was really fun to do.
Are you serious that you have a post like that? LOL. Trying to look for it. Never seen it before. That's ironic.
