you really want to see the backs? ok, you asked....
how neat it is depends mostly on the confetti content
here is grandma's bouquet, because the fabric is a loose weave, and the background is not stitched I am careful not to carry over open areas, this piece has virtually no confetti, so the back is fairly neat

this is Horses of Neptune, 100% confetti, and I carried alot. the back is a disaster, thank goodness its just the back. the front looks lovely.

the accolade is mild confetti, so the back is neat in some spots and messy in others

and this is Christmas Bear Wishes, heavy confetti and I learned to park. stitching row by row means all my carries, starts and ends are covered. the back is thick and I would not be able to frog this with any ease (so I am careful to avoid such situations) but I like that there are no long carries to snag on anything
btw thats the last time I take pictures of the back of my work. its the back, its not meant to be seen. if its not being framed I cover the back with fabric.
relax about the back of your work, the front is all that really matters.
