So, while waiting for good tissue paper to arrive from EZ Built Models, I spent a buck on some domestic tissue at DollarTree. I built a frame, and started fussing with it.

The tissue is relatively heavy, comes to about 18g per square meter. To get that figure, I removed the wrapping, and weighed the whole lot. The packaging gave the square meters, so I could calculate from there.

The tissue is pretty strong, and doesn't seem to bleed. I have only subjected it to water and water based adhesives however. I don't have any airplane dope on hand. It doesn't really seem to have a grain, and tears straight in either direction. I have only experimented on Yellow so far.

My frame was made of fairly hard 1/8" balsa. My initial test was just the square frame with 1 diagonal brace. I used Elmer's Clear to attach the tissue, thinned 1:1 with water. The result was pretty good but even after water shrinking there were corner wrinkles. More concerning was that the frame came apart. I used Titebond III, and I think I may have microwaved it to speed up the glue setting. This used to work fine for original Titebond; this new version, not so much.

How about pre-shrinking first and then attach to your test frame. Take into account
too that your test frame is unlike a structure say like a rudder that has shorter support
strips with less give area. Also, can you see any grain direction?

Yes, I think I will give preshrunk a try too. Here's a pic of the tissue with light shining through.
