I gave up on my rose.
I ordered some thread that I believed was comparable to size 20. It arrived and turns out to be more like size 3 crochet thread. There isn't very much on this ball so I went in search of small,quick crochet projects on Pintrest. Then I turned to Youtube.
Then I changed were the knots were joined and liked the look better. After adding hardware, it was promptly claimed by the youngest daughter. There's enough yarn/thread left over to make another but I lack the motivation to continue.
My two girls had a crafting session together and made some valentine buckets from Dollar Store stuff. I am so grateful that they were more considerate when crafting in the Momcave. They even cleaned up after themselves.
