Mixing the glue and water to make your snow globe tumbler is one of the most important steps in this process. The ratio of glue to water is 1:3, meaning you will use 1 part glue and 3 parts water to create a mixture that is thick enough to adhere well but not so thick that it’s difficult to work with.
Mix them well and let them sit overnight or for at least 10 hours. The longer you leave it sitting, the more time it will take for the mixture to thicken up nicely before applying it to your snow globe tumbler.
