Auction day today, and my purchase came in under $3. Plus, I finished binding a quilt, so it was time well spent if not money spent!
Some prices (pretty big crowd): Vintage quilts, ranged from $30 to $100. JP Coats thread cabinet $1300 (do these people check Ebay ). Vintage portable machine (15 clone?? I missed it at the preview!) sold for $15. A 1930s Singer 15 straight leg treadle, refinished (and not that well), plain black, went for $150.
I tend to go for the sad pieces that say "rescue me," so I picked up a ratty little orphaned oak dining chair for $2.50. Needs upholstery at the least, a new finish at the most, but it had good bones.
