Greetings. I've joined this marvellous site after seeing craftgrrl's embroidery hoop screenprinting tutorial linked to from here.
Well, I'm in the UK, and can't get Mod(ge?) Podge anywhere here. According to the Mod Podge website, the stuff can be cleaned up "with soap and water". Just like PVA glue, I thought. It looked like PVA glue (aka White Glue) wasn't so different to Mod Podge after all, so I tried my first design with it.
I did it last night, let it dry overnight, found a t-shirt and applied acrylic paint to it this morning. So far, so good - I didn't put quite enough acrylic paint on in some areas, but for a first attempt it was not bad at all.
Here's the bad part: I immediately rinsed the hoop with cold water, and gently rubbed at the acrylic paint to wash it off. It came off easily.... and then so did bits of PVA glue. By the time I'd got all the acrylic off, the glue had gone really sticky and gummy, and pretty much reverted back to its freshly-applied state.
I guess that's an awful lot of waffle to get to the point: Don't use PVA glue to make screens!
That said, I have a request: Has any non-US craftster used any glues that worked really well? Any brand names or specific glue types? I don't know why it's been so hard to find this information on the internet!
