So I went shopping:

125 each of 4-Bar reply card envelopes in "fossil", A7 invitation envelopes in "olive," and belly belts in "lemon drop." I picked up a glue stick, brown and white gel pens, brown and white ink pads, and a heart-shaped-hole puncher all from Paper Presentation.
You may have also noticed yellow Divine Twine, purchased after reading Miss Lobster's post, and the alphabet roller rubber stamp from Etsy that I picked up after reading Miss Stripes post. Yes, I bow down to the inspirational powers of fellow bee bloggers! Thank you ladies!
I have the tools, now let's see if I can build something with them...
Are you apprehensive or anxious about invitation assembly? Or are you happy to dig in?
