Stamp pads (any colors from here, here, and I got mine from here).
Cardstock (any colours).
Stamps for envelopes (just what we used)
Dry cedar (or other wood) - ours were 1" thick boards.
A scroll saw (get one. They are super noisy and a little scary the first time, but a major game changer).
Linseed Oil - this stuff is great...we finish 90% of projects with this.
Acrylic paint (red and gold, or whatever colours you like - I think turquoise would be super cute).
