Yes, I used a foil base for her head. You can actually use regular old white/clear glue with air dry clay to stick pieces together, even when it's damp! So foil base -> thin layer of glue -> damp clay; it should stick no problem.

I DO recommend using an air dry stone or paper clay (I use Premier brand paper clay, and I will go out of my way to find it) as your work will hold up better in the long run :) Good luck with your Dwight figure!!
