Bubble hash

I’m about to do my first run with a very dry amount of dry trim. I have the 8 bubble bags with pressing screen. What’s the best method to use when pressing and drying, I’ve read to squeeze bags out with towel but I’m afraid to lose product. I have more high grade bud/trim in the freezer but I wanted to practice first can this be made into hash oil? Any recommendations on how to make feco I bought a small crock pot today. Thank you!
