I'm a bit late to the sidestep fold party, but now that I've got the hang of it I'll be using it more often.
A couple of quick tips:
1) After cutting the kit base card, stamp the "inside" sentiment on the back *before* adhering to the sidestep base.
2) After cutting and stamping the kit base card, attach it to the sidestep base with thin lines of glue on the bottom edges only.
