I’m probably the only one who doesn’t know this and I thought I knew the answer yesterday but this morning, I’ve been so confused.
If a pattern says it is going to be 60 stitches high and 170 stitches long, and stitch over two threads, I was having the hardest time being sure I knew what size fabric I needed. It’s kinda like daylight savings time . . and you know how I struggled with that! About the time I thought I knew in my head what I needed to do, it was lost before it got to the computer to place an order.
So, I googled it and found this calculator. Perfect! Answer is there and I don’t have to rely on my own brain.
