I need to know what this decrease pattern means. It says to work k2tog, this I get. Then it goes to say "decr4 sts, evenly spaced, across every 18th row 5 times - 83 sts. I thought it ment k2tog evenly twice every 18th row. Close I hope.
I think it might as well mean
1. Step: k2tog and then
2. Step: Decrease 4 stitches evenly spaced in the row in every 18. row and do this 5 time. Having finished all of that you will have 83 stitches remaining.
May be it helps to just calculate the number of stitches remaining for each interpretation you find. That's what I normally do when I can't figure out what is meant :-)
