Here's the design I made for the invitation in Illustrator:
And here's the Gocco printed version:
I love my Gocco, but this was a tough project! I had plenty of supplies except for bulbs. Based on info gathered from searching the internet, it was suggested that using #5 or #5B flashbulbs would work as well as Gooco brand bulbs. I ordered some of both from ebay, and I'm not convinced they work as well. I used the blue filter, and properly prepared my masters, but the screen came out pretty clogged - resulting in a more, shall we say... "textured" print. Overall they came out pretty cute, but I need to get the proper bulbs next time.
