And I do have a question!
About the practical rotary cutting and where to put my hands for the first cut. The second cut, on the right of the triangle ruler, is clear to me, I hold down the ruler with my left and push away from me with the cutter in my right, as normal. (Or as is normal for me at this stage, I never took a class in this so what do I know...)
For the first cut, along the left-hand edge of the triangle, I've ended up twisting myself into a cord to hold the triangle with my left, then reach around my left arm with my right and cut. I'm cutting towards the point of the triangle because I found starting the cut from the point of the triangle (which is less twisty for me) too difficult. I wish I could take a photo of me doing this...
Does my description make sense? I'm wanting to cut more and am wondering whether there's a healthier way of doing the left-side cuts!
