Well this is what blogging will do to you. I would have been perfectly happy just ordering my paper pieces online and doing my little project. But with a blog I have this sense of responsibility. What if I get someone excited about the pattern and they can't buy the templates? So I've wrestled with my ruler and printer and found simple-enough solutions to share.
For the diamonds: You're going to want about 500 of these dudes unless you join your units as you go, and even then you'll need a few hundred. So let's rustle up some scrap paper. Using either 8.5'' x 11'' or A4 paper, you should get 15 diamonds on each page that you print. You can actually get 30-60 diamonds for every printed page though, if you use the little trick below.
First, go here. Choose your paper size. Change "minimum border" to 0. Change "block size" to 2 inches. Download the pdf, then go to print the document. Make sure that the "page scaling" setting is set to "none". When it's printed, measure a side of one of the diamonds and make sure that they have in fact printed at the right size.
Now get another 1-3 pieces of scrap paper, and put them under your printed sheet. Staple the pages together. Cut out carefully along the lines with sharp scissors. You may decide to use thicker card stock paper, and if so you'll probably want to cut just two sheets at a time, but I was able to accurately cut four sheets of regular weight paper at once.
To draft the hexagon: you need a piece of paper, a pencil, scissors, and your ruler. You'll see that there is a piece of painter's tape just beneath the 60 degree line on my ruler. This made it easier to see and also provided a slight edge that made aligning with the edge of the paper easier. I recommend it.
The test: do two of your diamond sides equal one of your hexagon sides? Perfect.
However you get your paper pieces, I'll be back to walk you through cutting the fabric soon!
