What a fantastic idea! I have a bunch of clear, 2 pocket sheet protectors, made to hold postcards and those would be great to keep 4 x 6 cards inside! I'd like to make up my own cards, make them to size, a bit bigger maybe out of card stock. I am excited to start this!
Regarding the Impulse Sealer, you can buy one from
ebay for around $25 with free shipping. What's great about them, is it has a dial on the front to adjust the heating element. But what I really like, it does not stay or keeps hot. It will only turn on (the heating element) when the top bar is pressed to the bottom, as soon as it gets to dialed temperature, it automatically shuts off, even if you are still pressing the top bar down. For the price, it's good to have if you like to dink around like I do.
