Pros : Good surface to solder on, holds tacks securely
Cons : Hard to stick pins into, have to hammer tacks in
Other Thoughts : This makes a decent surface to work on, but it's a little too hard to use straight pins on. It can be done, but they're really hard to put in. And, the pushpins that come with the Morton system, well, I have to use the hammer to get those in all the way. Insulation board makes a much better surface. Also, I bought several sheets to cover a large surface with and found that they're not a uniform thickness, causing my work surface to be uneven. So, I'm going to find a big sheet of insulation board instead.
