In answer to all the questions on printing on tissue paper and because I can't work out how else to let you know.I'll answer the question here.I fold my tissue paper over a piece of printer paper and attach it on the wrong side with double sided tape to hold it in place.
I use a a draft or normal ink setting on my printer as the best setting can wet the tissue too much and cause it to clog up the printer..So start with draft and work up.
This is how it looks when it comes out with the backing paper attached.
And after the backing paper is removed.
It really is a fun way of adding images as it blends in with the background.
Hope that helps..
