I started from opposite sides, but I don’t know that you have to do that. You’ll bring the yarn over the previous color each time on the hypotenuse. The photo on the left is wrong because the red yarn should have been on the other side of the nail. I had to take the out and redo it. This is much easier on the square, IMO 🙄 But it isn’t difficult here, either. Getting started is the trickiest part. If you don’t have a velcro dot, you might want to half hitch around the beginning nails. That’s pretty much it. If you have any questions you can email me: dorleska at tds dot net 😎
