My hubby made a tank a few years ago with plexi glass, he used aquarium glue. His was 120 gallons so it was pretty thick plexi glass and he used screws. I'm sure the glue alone would hold it if you are not using water, but should be safe for you animals if it is for the fish.
I'm an owl freak too! Absolutely love this owl! I would love to know if anyone has ever seen left handed patterns? I'm self taught, I can crochet any circular or fillet by just looking at it. But something this fantastic would deserve a pattern. Kudos!
I had the same problem as craftydeb. I think that they purchase designs from many digitizers. So, when one person doesn't have problems it might because it is from a different digitizer. I had one 3x3 design that was over 70,000 stitches.
