Thank you for this…I was pressing between parchment paper with a bottle of hot water and it would take for-absolute-ever but would eventually ball up. Definitely gonna try this method, I have a perfect rolling pin for it.
I had often thought of grabbing a few grams of my dry sift kief and sitting down for a “This Old House” marathon while making hand-rolled hash someday. 
Gonna try your process first, though! 
@TransplantedFarmgirl please tag me if you have any questions!!! I’m sorry for the delayed response, but I was very busy yesterday afternoon and evening. Normally I live on the forum. I hope this method helps you. There are some people who use turkey oven wrap instead of the parchment. It is a poly product so it keeps the hash more compressed while heating you have to cover it in the oven with a dampened cloth, but I find the parchment works fine for me. 
please tag me if you have questions or just want to tell me how you made out with the process!!! 
be safe fellow cultivator!!!
Can do! Thanks again
