Your work is really beautiful
thank you for sharing. I'm an amateur linocutter and I use speedball products. Speedball water-based block printing ink is what I have. For paper I've been using Sumi-e paper, not sure what the brand is. It's a thin Japanese paper which is meant for brush painting/calligraphy, but I've found it works well for printing.
The process goes like this for me:
1. squeeze out some ink on a piece of glass or metal (paper plate works in a pinch)
2. roll out the ink with a brayer (mine is speedball as well)
3. when the ink makes a velcro-ish noise it's ready to be rolled onto the block
4. roll the ink onto the block with your brayer
5. place the block face down on your paper and press it down
6. flip the paper over and begin to rub it. I use a wooden spoon for this. If your paper is thin, you should start to see the image come through the paper.
