bristles on the brush. I got a lot of it in, but not all of it! As you can see, the left side needs to have a couple more bristles at the top. The right side still needs a few more fill in stitches at the top, and, the entire cream color of the top need to be filled in with the split stitches so it will blend. I hope you get the general idea, though.
Thanks for all the great comments on the Circles box! They are quick to finish when you can do a lot of spraying!
