That is the same setup I was using to make hemis but the time saved buying hemis by the case outweighed the small price for most sizes.

But you do an all around nice job, I to like to make what I can before buying especially with the price of tooling for this hobby.

Those are beautiful! I like how the break turned out on the BP broken green peony, but that red peony was just about perfect. Sweet work!


It's only fireworks.

Great shells. You can definitely see the BP burst hanging in that green peony.  Heard people mention about the charcoal burn "hanging" but never really noticed until Niladmirari's shell.

Very nice shell. I couldn't see the yellow stars, I see red. Is rolling with phenolic resin the same as with dextrin/water? I'm eager to try rolling with phenolic resin and alcohol, but what about composition sticking to the roller?

Absolutely beautiful, I like watching your shells. What is your carrier used there for burst? Which technique are you using to paste. Love the ingenuity of the home made hemi's.
