After your sheet is dry, cut it to the size needed for your dio. Since this was a demo, I just cut a suitable rectangle of material, rather than try to measure something that is scale. Use a very sharp blade for cutting, of course. Unpainted tissue prefers to tear rather than cut, but with the acrylic, it responds very nicely.

To get the "fabric" to conform to your model, re-wet the tissue and apply it. The color doesn't soften and run and can be done and redone as often as needed to get it to look right

Although the paint doesn't run, the tissue becomes fragile again, so be careful when adjusting it on your model. Any protuberance will snag the tissue! I know...the Kingstrom handles on my Pfalz's Spandaus were a convenient place to hang up!

Here is the tarp dry and settled in.

A coat of thinned white glue after it's all done will ensure it stays in place. The nice thing about white glue is that you can re-wet it and move it around just as much as before. You can add ropes, grommets, whatever to the tissue because that paint really imparts a lot of strength. I hope this has been of some help and comments are always welcome, keep on modeling guys!
