Hi, I sent Judi (Green Fairy) the bat with the quilt. It was Hobbs Heirloom 80/20 blend. I have since received the quilt back and seeing it in person just floors me. Her longarming is just drop dead gorgeous. I love what she did for this quilt. I also asked her how long it took her and she guesstimated around 20 hours. It certainly shows!
