I was the lucky recipient of your card, which I will cherish forever!
P.S. As usual, I’m very impressed by your efforts and artistic ability.

You can definitely make printer-friendly paper. In order to control the thickness/weight of the paper, just add more or less of the pulp to your tub full of water. I usually add 2-3 blender batches to a sink filled about 4″ with water. This comes out to roughly a dozen sheets.

Another thing to consider is the amount of starch you put into the mixture, which will make the paper less flimsy and likely to tear. A couple tablespoons of liquid starch should do the trick. For sturdier, cardstock-quality paper, add more.

Finally, you might want to trim the edges so that they’re straight. When you don’t, it has a more handmade feel, but this might not work as well with the printer.

Do you think the paper would hold up to being run through an inkjet printer? I could imagine some pretty cool photo prints done that way.
