I would like to start basing my figures, but I am wondering which kind of glue to use.

The figures are plastic, from a normal sprue and the bases are round and made of wood. I was thinking PVA glue but not sure if that will hold the pieces since it may become brittle.

Do you guys think that super glue would do the trick?

Also, should I base the figures after or before the base is completely done? Meaning, should I add the grass, dirt, sand, rocks, etc or wait until the figures are in place?

Thanks!
