I started hand quilting my UFO for the challenge and it is not standing out like I pictured it. I picked a medium green section to start with and used dark brown DMC thread. I got half of one leaf done and was not happy so I took the stitches out (took three times longer than it did to put them in) I used one strand of the floss. I am wondering if it should be thicker, BUT I hesitate to start again. If it is still difficult to see, I will have to take it out again. I am don't know if I should just go with ordinary white quilting thread. Can you give me some opinions?
