a few things: 1) Is it ok to anchor the finishing cross knot on a cross. Or should i anchor it to a main? 2) Is there any limit to the distance to the center cross that i should tie off the cross knot? ie: with 20 crosses (in this case anchoring the cross to another cross) would it be bad to anchor it on the 4th or even 5th cross from the bottom? (i have it anchored to the 3rd but it is rubbing on a main. too close) I hope I am making sense. PLEASE AND THANK YOU for your help all!
