1. Supplies: scissors, etching cream (we used Armour Etch ), mason jars, contact paper, sponge brush, gloves for protection. 2. First, cut out large circles in the contact paper. 3. Then, apply them all over the mason jars. 4. Next, following the detailed instructions of the etching cream when applying it to the mason jars. You want to pay close attention to the instructions on the cream since it can be extremely dangerous if it comes in contact with you skin. Follow all safety guidelines. Here's a link to the instructions we used to learn. We leave our cream on for about three minutes. 5. Next, remove the contact paper and wash cream off in running water. Use a sponge and don't be afraid to really scrub it until the cream is completely gone. 6. All finished! Enjoy your new glasses. Your new glasses are dishwasher safe.
