I would finish it, sometimes what we see in our mind doesn't always look the same when actually done. USe a sheet or tablecloth for the backing and throw in a poly batting, Practice that FMQ design you have been afraid to try and donate it to the local women's shelter, hospics center, dog sheter (you get my drift) and try something else. If you do not want to finish it sent it to me and I will finish and donate to my guild - our last donations were to a transition home for men who had returned to society after extended stays in the prison system.
Good luck!
