If you haven't used it before, E6000 glue is phenomenal. It's such a strong glue, which is why you should use it in projects where school glue isn't enough. Like this one. School glue will not adhere the heavy wine cork halves to the glass and the wine cork halves with slide down Frankenstein's face. A couple dots of E6000 glue will hold them in place. What's great about E6000 glue is that when you close it and re-open it, the cap doesn't get stuck, unlike Krazy Glue and other similar glues. Although those are multiple use packages, it always seems like the first use of that glue is great and the rest are less than great. Plus, sometimes that glue wears off. And hot glue sometimes falls off, even if it's hot enough. Plus, hot glue is so thick that you'll end up with a gap between the wine cork half and the glass, and that doesn't really look that great. I've never had any of those problems with E6000 glue and use it quite a bit.
