A little while ago I posted a blog where I had used PVA glue as a resist.
I had a good result, but blimey it was hard work.
I tried it again but with a different PVA glue, this one aimed at children. It was easier to apply but it was not successful as a resist.
At that point I sort of dried up. That was part of my City & Guilds and I think I then moved on to something else.
Anyway, Daughter has found this post and I thought you might be interested. I have not tried this, but in this post flour paste applied with a simple icing bag is used to create a resist.
Like my own experiment, this technique did not use a "submersion" technique but used Dy Na Flow paint sprayed on (I painted mine on).
I have not tried it yet - I will do and will post the results. But in the meantime thought those readers who like an experiment might be interested.
And as a bit of a post script you might also like this - a simple stitched book but with a great idea for the cover.
