Default Can I make my own silicone molds?

I just recently purchased some Silmar 41 resin that I intend to use for casting in-tube blanks. I'm interested in making my own silicone molds to start off with (I don't want to purchase any yet). Does anyone have any suggesting as to how I would go about making my own silicone molds? Is there a way to use something else besides making my own silicone molds for casting in-tube blanks?
Any help would be greatly appreciated.
Thanks!

You don't have to make silicone molds. I've seen molds that use vertical pvc pipe. You just need a way to keep the tube centered as you pour the resin.



I'm working on making my own molds and the biggest issue is the cost of the silicone. Its heavy stuff and for the smallest amount S&H can be expensive.

I just bought the small kit from Micheals with a 50% off coupon and I think I found a local art shop that has Smooth On products.

I've also tried using silicone caulk with various mix ins to get it to set quickly and it a mess. It maybe helpful for somethings but again its a huge mess.

I used Smooth On Dragon Skin silicone for making my molds.
