Using ET Lite has been so hit & miss for me - the bubbles, weather & temperature wreak havoc on my caps! I have used polyurethane stickers from previous group buys and they were okay in a pinch but I disliked the way the surface of the sticker was tacky and somewhat "gummy" feeling (not sure if maybe I got bad batches of them?).
I purchased some from Sweet*Lilly*Rose's last group buy, and I'll admit it was mainly because the price was really good. They sat on my craft shelf for a few weeks and I pulled them out last night for a rush order. OMG I wish I'd bought them from her sooner. Crystal clear, strong bond, and best of all the finish is wonderfully smooth and glassy. Super impressed with these drops (and she shipped quickly once the drops arrived to her).
I'm officially a convert - no more measuring, mixing & breathing stinky fumes for me
