Just bought the wilton Gum-Tex and I have my powdered sugar BUT I now see that the recipe calls for glucose. Is there anything that might be able to use as a substitute? Maybe corn syrup?
Try to use the white corn syrup. Regular will darken the gp. You may also need a bit more ps as corn syrup has more water than glucose.

definitely corn syrup. It's very hard to get corn syrup here, so I take glucose (easy to get) and add a tiny amount of water to get it to the same consistency as corn syrup, but hardly any. Most people I know here just use them interchangeably, and don't even bother adding the water.
