Paint a layer of mod podge around the entire glass. Then dip them in modpodge ( I put mine on a paper plate to the side, you don’t want random yarn fibers hanging out in the mod podge canister later) and stick them on your glass. The mod podge makes a nice clear texture So you want it to be textured all over.
That’s it! Now I have some funky labeled jars in my bathroom instead of just plain ones. Have fun crafting!
