I chose heavy watercolour paper for mine, and these particular sheets I had done a splatter technique with fabric dyes, not realising that for this particulad dye to be fixed I would have had to soak the paper in soda ash. So my green splatters moved and stained as soon as I tried to paint and draw over them, and for the postcards I toned the green down and also fixed the dye with a thin coat of gesso. You can see how the green moved in the green streaks in the next picture.
Following the Gesso I gave my paper a nice coating with Gelatos, an item in my stash I am now using more often in my pictures. I first smudge them more even with my fingers and then go over them with thin white acrylic paint.
I think I also used my brayer and white acrylics in my layering process and I ended up with some nice soft but still bold colours. Next I sketched random flower outlines on my cards and filled them in wih thinned white acrylics again, They looked a little ghostly to me and I really liked how they turned out so I decided not to paint them any more but instead I tried to enhance them with a coat of matt black.
Now they looked even ghostlier, if that is even a proper expression. But I think you can see what I mean.
And next I did my doodles and outlines with black and white paint pens.
During this process it turned out that a few more people were participating in the postcard swap than I had anticipated, and also I had falled in love with one of my own cards (making it impossible to send it to someone else) so I had to gesso and prepare another sheet of watercolour paper and make some additional cards. Then lastly they all got a protective coating because I wanted to make sure none of the Gelatos smudged in transit, you can see all my cards in the next picture. The late stragglers I made are still missing some doodled decoration but I figured the paint pen could stick to the coating and would be safe on the journey.
And this is my favourite card I kept. Well, I didn‘t really keep it at first, I mailed it off with all the other ones just adressed to myself. I also had one additional card left over and I mailed that one to my Mom (Hi, Mom...), she had mentioned that she never gets any nice mail at all...
