Masking Tape is Your Friend.
In order for the wood glue to really work it’s mojo, you have to clamp your join well. But in the world of miniature dollhouse things, unless you find itsy bitsy clamps, this can be a challenge. Enter… masking tape. Instead of relying on expensive tiny dollhouse clamps (do those even exist?) to hold the wood firmly together, just ‘clamp’ it with some masking tape. You’ll get the ability to clamp odd angles and tiny pieces, and when you’re finished the result is almost as solid as if it had been clamped over night.
