For my Nuchalawoyya sweaters I started off with American Apparel sweaters. I like them because they are light weight and soft. I know in Alaska a lot of people want heavier sweaters in the winter, but I think the sweaters are small enough to throw on under a jacket.
Before printing sweaters I have to make sure there's a lot of tact layed down. When there isn't enough tact the sweater can lift off of the surface, which can really mess up a print.
I lined the sweater up where I wanted it, and made sure to press down, so that the sweater would stick to the surface.
I printed the Nuchalawoyya and stars layer first. I chose to print this layer with white ink to make sure that it stood out from the black sweater.

I didn't like my first red color so I had to clear the screen out and start over. The color wasn't bad it just was a little too dark. I mixed in a little bit of yellow, as suggested by Gary, to brighten my red up a little bit.

The red was still a little dark so I had to flash it. This means that I put it under a heat source to dry the ink, so I could print on it again. I wanted the red to be bright, but no so bright that it competes with the stars and Nuchalawoyya layer.
After finishing the Nuchalawoyya sweater I put it in a rotating oven. I would show this but this blog only allows me to post a few pictures per post. The oven dries the ink and cooks it into the shirt.
After printing several shirts I noticed the white ink was starting to gunk up. The finish line was really close with just 7 sweaters left to print. Oden the owner of Nomadic Stars, where I printed these shirts suggested that I take the white ink out and thin it out, then reapply it to the screen. Because the printing process was taking a long time and I still had another design to print, my initial tendency was to just power through the gunky ink and get it done.
However I remember what happened in my last print when I tried to just go through some gunky ink, and how it messed up my last couple of prints. So I did what was suggested. It may have slowed me down by half an hour, but it payed off.
The final result is shown below.
