Thanks. Sometimes I don't turn the edge. But, I have discovered children pull on the blankets, stretching the edge enough to pop the stitches, even when I use a forgiving zig zag type stitch. The other reason I turned these was to give a more pleasant feel to the edge. Don't ask me what that means... I am repeating what my grandchildren call it. They like the edges turned.
I love fleece to make their names because it doesn't ravel and it is easy to cut letters.
No serger but do have a lot of stitches on my machine that are similar ... just takes longer. Some of these were for January birthdays for grandchildren, some just to give away ... using up the fleece stash.
