Yes, I have. I have many tops as well as blocks that just said "take me home". I may or may not get them finished but as someone else said they have a good home and will be well taken care of. The other reason is that for me they are affordable (a completed quilt is usually waaay out of my price range). They also take up less room if we are traveling and happen upon an antique store. I have a notebook that I keep a list of purchases in. I list a brief description of the top, measurements and colors. If I know the name of the pattern I will put that in along with where I bought it and what I paid.
