I am a DIY'er at heart, so I know where you are coming from wanting to make your own plugs, but in my opinion it just isn't worth the time it takes to make and cure them when you can purchase pre-made / cured plugs for so cheap.

Yeah you're right but it gives me something to do and I found some really cool molds to create domes for my favias. I'll post some pics when I'm done.
