I'm looking for advice on small labels or stickers I can put on my bowls that will stay, not leave a mark and not require mineral spirits to remove. When at market shows I put a business card in a bowl with the price or I put items in sections that are all the same price. I've tied brown string around them when I'm not there to attend and watch them but that's a challenge to keep in place. I'm considering putting some bowls in a consignment shop and want some way to put a price on items and know what's been sold. I use walnut oil as my finish so not sure what label sticker might work best or at all.
