I am absurdly pleased with how these halves came out. Some parts of sewing them into a 3D shape were not easy, but not too difficult either.
As mentioned, I used a mini-charm pack so the backs don’t look as tidy as my half hexies do. I don’t care. I am using pretty supplies I have. I also had no time to pick out fabric and cut small pieces, so the mini-charm pack worked well.
