E600 is my adhesive of choice when securing the cork or lid into the opening of each bottle top which protects the contents. Inking the cork, before gluing into place, helps me achieve the aged-look I desire. This is an old bottle with a fancy wine bottle cork.
I found most of the labels for the bottles by doing a Google search for “Harry Potter potion labels.” A few were found on eBay, Etsy.com, Scrapbook.com, or they were cut from a sheet of paper (see below). I distressed them with Walnut Stain ink, and many were crumpled and ink added to the wrinkled ridges to give them additional aging. Clear contact paper was added over most labels to preserve them (leaving 1/8” around all edges to help with the seal). This label has a string tie (it goes through eyelets) that is knotted at the back of the bottle.
Because Floo Powder is used by Harry Potter and his friends for traveling via chimney's, the "J" or "journey" token attached to the wire closure seemed an appropriate reminder.
