Split-loop potholder pattern

I saw an image of this potholder on Pinterest, but I wasn't able to find a chart for the pattern, or any indication of who made it. (So, thanks to whoever came up with the design!) Because the potholder was on the loom, though, it was pretty easy to figure out.

Basically, you'll need to think of one loop as two strands. Each row starts out slightly differently, but then you will simply go over or under two strands all the way across, finishing the row by either going over or under one loop or one strand (this will become obvious as you're weaving). After the first three rows, the pattern repeats.

Here's how to make it (for an 18-peg loom). I think it could be adjusted easily for a 27-peg loom.

Warp (vertical): Alternate three red and three white loops.

Weft (horizontal): All green loops

First row: Go over the first loop, under the next loop, and then continue across as you would for a normal weave. (No split loops.)

Second row: Under one strand, over two strands, under two strands, etc.

Third row: Under two strands, over two strands, under two strands, etc.

The pattern repeats

Here's a close-up of the first four rows:
