I am using a fry pan as suggested by SparkFun. But instead of an electric fry pan I am using a thrift store Teflon pan on the gas kitchen range.
Some day I would like to build the toster over along with an etching tank... but for now the process works. The solder paste stencil cutting is doing well. Now if only I could plate holes.
I cut the stencil using a CRICUT scrapbook cutter. I figured out how to in this thread.
I have switched from a laminator pouch to a overhead transparency to get a thicker paste layer. It took 4 passes on medium pressure and speed to cut a clean stencil.

A member asked me about SMD solder paste in chat. If you have never seen it under a microscope here it is in 200X. aka solder balls in flux **broken link removed**
