I made this paper back in the summer for an exploding box card that I did for mum's birthday, which I finally sent to her a couple of months late, but didn't post in case she saw it before it arrived. Eventually I'll go home & take a pic & post it for the relevant day but not yet, there's too much ice & snow on the roads. Anyway, I got a thin sheet of cartridge paper and pasted one half in torn up and one half in cut up pieces of various shades of red/orange/yellow tissue paper (a co-ordinating colours pack from Paperchase that I've had for over 10 years). I used most of the paper for mum's exploding box, but have taken some of what's left for this sunshine catchup card.
The backing is part of the torn paper half, and the lettering is part of the cut paper half, which helps make the word stand out. I think. I hope.
You can take a piece of acetate/thickish but bendable plastic and paste the tissue paper straight onto it with diluted PVA glue, then peel it off when it's totally dry, which gives a translucent quality, that you can also stitch on.
