Funny you bring up this subject! I did a wall hanging earlier this week with the about the same idea. I did find that when I used a glue stick the items did not really stick in place (but I did a blanket stitch around each) and some of the circles did have some tucks in them. Since this was a wall hanging for my sewing room I did not take out the tucks. I also FMQ around the circles. Now this was the first time I worked with circles. I found it will be better to fused the circles next time.
