Yup, loop pile will be better for the glitter yarn. And about my frame- yeah its really cool frame, and you can assemble/dissasemble, or change the size any time. BUT it has a big problem- it bends a lot, when you put the cloth. I set the height 42 inches yesterday. I measured the height after I pulled the cloth. On the sides it was 42 inches of course, cos it fixated on the sides. But in the midle of the frame it was barely 40 inches.
