Once the pieces are all fused to the interfacing they're not going anywhere and the whole thing automatically folds on the seam lines making it very easy to stitch your 1/4" seam.

I will say this: The seam is "thicker", meaning it appears slightly "puffed up", but I found that to be a pleasant looking thing, and once I did some SID on the squares in the center it actually accented the floral wreath somewhat. I'm just about ready to bind it, then need to add a hanging sleeve and it's done!
