The pattern is 50% larger than normal, but EVERY piece of the pattern is that size.  So if you were using the standard printed out sizes, no changes would be necessary.

And yah, just a normal snap. 

i watched your fulll video... you are using polar fleece.........

Yah, it's Blizzard fleece.  It's pretty good stuff.  It doesn't hide seams as well as antron, but it's also quite a bit easier to get a hold of and not quite as expensive. 

ok, a few more questions so how do you attach the snaps to the fleece? and do you just follow the pattern normally but leave that part open? and do you modify the standard fleece body pattern at all to make it fit or anything like that?

I already mentioned how the snap is installed.  You have to buy a tool to do it. 

The rest of it, I'm just going to say experiment and see what you come up with. 

Actually you can also buy snaps that you can sew on if you don't want to invest in the tool.  The ones that you use the tool on are a lot like a snap rivet or grommet and is embedded in the fabric.  It is a l much cleaner version of a sew on snap.
