I have seen this tute a couple of times and don't know where it was located. I have looked through a lot of u-tube listings but don't know what it's actually called. There was a circle cut out in a square piece of material and it was filled with another material cut in a circle. I think this circle was 2 pcs. sewn together and turned inside out and pressed then somehow sewn into the hole. I know this sounds like jibberish but when I had it bookmarked I didn't know you were only allowed so many to be saved. Could you wonderful quilters help me out? thanks, Glenda
