To whoever recommended the Advanced Tape Glider by Scotch for assembling invitations! I'm in love with you and am eternally in debt to whoever you are!
I'm still putting my invitations together (the printing and cutting took FOREVER), but I'm now making amazing progress because of this thing! I bought it with a 50% off coupon, but I wouldn't have minded paying full price if I had known how easy it is to use and how fast it makes the assembly process.
