I am working on a queen sized quilt that has appliqued vines all the way around the outer edge- does that count? I've done some pretty large appliques. as for size to recommend???? any size you want to do- guess i'm really not understanding the question. I've never really thought about any restrictions concerning sizes- to me with applique- the sky is the limit- doing applique makes it possible to create anything you want- in what ever size you want it- there are no restrictions.
