it really is a simple technique and the results are limited by your imagination. I hope you give it a go at some time.
glad you enjoyed it and it is informative for you.
I hope that you try it sometime. It is fun.
it is perfect for kids. Although they could get carried away splashing paint around
if you have the tap running too hard it will. It will also wash off if the alum is not completely dry to begin with. I know......experience
You know you are doing wrong when the colour comes off in a sheet. Actually if you wash too much the colour will come off. So I wash just enough to get rid of the carrageenan, clear the colour where it has run into other colours, and to make any white be white again especially where there are the bubbles of soap were.
good luck with the degree
never heard that you could do this with shaving cream. Curious.
you are welcome
I think you need to use something that is absorbent. Firstly for the alum to size the paper, it coats the paper with aluminium sulphate which loves water. What happens is that when the alum dries and you rewet with the paint, it sucks the paint into the paper. I think canvas board would resist that. Try it but I think the paint will wash off when you go to rinse.
