I've been asked a bunch of times if my peyote and brick stitch patterns can be cross stitched or used for loom beading. The problem is, they are a completely different kind of graph since they are offset. I thought about the problem for a bit and came up with this quick and easy way to convert graphs.
You'll need a peyote or brick pattern to convert, some plain graph paper, and colored pencils.
We are going to work with this simple rose pattern.

As you can see, it's offset, it won't fit in regular graph paper. So you'll need to be able to offset the regular graph paper. The best way I've found is to use 4 square units to represent one bead, and create the offset that way. You can see what I mean here. Each 4 square block represents one bead.

If you are working from a brick stitch graph, you'll turn that 90 degrees.

So now it's time to pull out your colored pencils, and color in 4 block units for each bead. When I was done, this is what I wound up with.

So all those patterns you've been asking me if I can convert, now you can convert them yourselves!
There are some drawbacks to this method, since you'll wind up with something that's 2 times as long, and 2 times as wide as the original, and it's a bit blocky looking but it's the truest way to convert a pattern to something you can use on the loom.
I use graph paper and a graphics program to create most of my patterns. There are a lot of great beading programs out there to create graphs from,and some of them convert between loom and peyote stitch so if you want to do your own graphing, that's a great way to convert. You can fix individual squares as you like. However, you can't just open a pattern you downloaded off the net in one and create a loom pattern.You'll have to color in the beads in the program, then switch graph styles.
Here's some little graphs you can use. The peyote one is 25 beads wide, and the plain graph is 50 squares wide.
