I purchased about 8 patterns from HAED (what was I thinking). They are beautiful, but look a bit challenging. The instructions call for linen 25 (which I have purchased) with a 2 over 1. I think that means 2 threads over 1 (not sure what to call the 1). I assume these will be very small cross stitches on the linen. I have seen many youtube videos illustrating 2 over 2 on linen, but I have never seen a 2 over 1 on linen video. Please help. It's been 30 plus years since my last cross stitch project. I hope I have explained my dilemma clearly.
