The top picture shows a plate made with stencils and modelling paste. The band across the top was done with Golden crackle paste which, as you can see, produces a craquelure finish when it dries. The one in the second picture has stencils and modelling paste again with the addition of glass bead medium across the top.
I have to say I had mixed results with these when I used them on the gelli plate. Joan's post here shows some excellent prints using this idea and I was hoping to have something similar to share. However, for whatever reason, I wasn't totally satisfied with my results. The patterns didn't always show up particularly well on paper and that may be to do with the way I constructed the plates - perhaps the modelling paste isn't even enough, or perhaps it was something to do with the heat or my choice of paper, I don't know. I will try again though and report back, and if you fancy having a go yourself I highly recommend the video I linked to above.
Anyhoo, here's a card I did make successfully with the texture plates - gelli printed and collaged!
