Ok now I see what you're talking about, although quite honestly I think once you get the whole quilt together it really won't be that noticeable.

In the future, you can mitigate that problem a little bit by making your folds smaller, more like gathers. Here is a video that I hope will show you what I'm talking about. She's trying to sell her tools (which are very nice and I like them, but you can use a stiletto, a sharpened chopstick, or whatever works) but the concept of what she's doing is what I think might click for you.

Welcome to this board. Great people here.

I agree, the turned fabric should be much narrower. If you don't like the wrinkles you already have, take your scissors and cut off the 'flap' of the wrinkles.
Welcome from western NY and happy quilting :)

Thank you for the help. I watched Jenny's video with the fusible on the back and I hadn't seen that so think I will give it a try as that helps me 'stick' the applique down once done. My folded under edges were 1/4". I measured accurately when I cut it out so not sure I can do much thinner there or I have nothing left. I also was looking thru my fabrics to see about making a lining and I noticed all my solids, regardless of color or brand, need 3 layers of fabric before they become opaque. However, any of my prints I checked do not have this problem and a folded under section would not be noticeable. It must be something about solids.... So I think I will try 2 layers of 'lining' inside the circle. I'm also going to try a thin batting layer as that also provides the opaqueness and I wanted rest of my buttons a little puffy anyway. I will post another photo when I have something that looks good.

You might lifting the seam allowance again. Clip the seam allowance almost to the fold. Then re-press.

I don't have much more to share, except that I think what seems like a big deal will get much less important in the context of a big quilt. Also, that piece shows the seams as you're holding it up in the air, however, I wonder if they would show after it's placed on the quilt with quilt top, batting and backing behind it. But stuffing it with a little thin batting would be cute, so go for it! :thumbup: If doing so gets too hard, I'd definitely see if the seams will disappear with the other layers behind it.

With some lighter colored pieces of applique, I sometimes cut the same shape of the finished piece out of white or cream fabric. Then I tuck it inside the colored piece to hide the seam allowance. A piece of thin batting or flannel would also be possible, giving it a trapunto look.

There are several videos out there that explain prepared edge appliqué. The interfacing method suggested would probably be easiest for your project though.

What about just using the same yellow fabric as the lining, cut to follow the shape of the seam allowance, then press it in place. That way you will have 2 layers of yellow that should look like one piece when finished.

I have always clipped a notch in the turned under seam so it fit together in an almost smooth full seam. I didn't explain that very well but I hope you can understand.
