Lookin good!
My mother-in-law gave me a basket top(top only,never finished) back in 1960. I don't know how long she had it, all she said was that she made it a long time ago. I have had it in my stash for around 50 years. I never finished it either. After seeing your picture I pulled my top out to check it and it still looks great. I am going to finish it and sign and date it so someone will know just how old it is. I also have another basket top, top only, that I bought at a garage sale. I got 4 garbage bags full of fabric for $10.00 and it was in one of the bags. I don't know anything else about it.
