My turn...

I was afeared these experiments would not go well, as we don't have a "Pro Chemical" here and though I went to two different shops, no one had any "print paste" just "base".  I tried a third shop, where they did have print paste, but no "SH" option available, nor did they have a "thick" option available. I bought it anyway, but when I opened it at home - it looked like white glue with a sticky pudding texture - nothing like Beth's and it didn't require any of the mixing process that was part of the linked instructions.

I  knew it wasn't going to work like Beth's did as soon as I opened it, but I tried a mixture of 4 tablespoons of the print paste to a mason jar's worth of urea water and blended that up. No thickening whatsoever occurred - it remained the same texture as it was after I mixed it (with some pleasant foaming action lol) - but I added the dye powder in the recommended amount of 1 tsp powder to one cup print paste mixture and gave it a shot anyway.

The resulting liquid was about the texture of whole milk, so using a resist of any kind would have been futile, but I tried to work a design on the screens and after my first pull (washed, dried and with an iron print for your pleasure [I got distracted by our new dog!) this was the result :

 

Uninspiring, but I can certainly work the cloth some more  (maybe some shibori discharging?).  My second pull on the same screen:

Which I liked much better.  And then I tried some smaller screens (8 x 10) with similar results:

Really just kind of a mess.  After doing 4 screens of  2 or 3 pulls each, I gave it up as a bad job. Like I said above though - these pieces of fabric can be rescued with some other processes.  And, not all was lost - I made some lovely painted, scrunched and shibori fabric pieces with the leftover print paste mixture that turned out beautifully!

I would try this again, but would have to order the proper tools for the job from the U.S. in order to get anything close to the results that the rest of you had.  I was also thinking about using a base extender as the "print paste"  as well - any guesses on how that might work?

No matter - as always, it was fun experimenting though!
