I actually used 3 5x7 card bases not envelopes for this mini album. Sorry for the confusion. These are sold at HL and are the Paperstudio large card pack, 50 come in the package and they sell for $9.99 but use your 40% off coupon for a bigger savings. You can use the envelopes to make a different mini album. Just think of how many albums you can create with one package if envelopes.
