I have a couple of the micron pens which I got at a local fabric shop. Most shops of this type have them. Mine were under 2 dollars each. They also have different thicknesses, so you might pick the one that is finer to write easier. I have made one with the muslin backing, but the rest with card stock like I use in my computer. It works great for the card side. Also we are to print or write however we choose the words POST CARD on it. When I made the one with muslin then I used my micron pen to write with, and to draw a line in the center. I made a little fake fabric stamp and added it. Then I sent it in a regular envelope. I am just silly I guess, but I just have fun making the back regular. I put most of my creations on the front side. Then again, I will probably do another that way too.
I actually have the front side of mine done, but have to put it all together. I won't tell all, but I tried a little shading this time with some colored pencils along with the main thing I did that's on it. It looks pretty.
