My personal rule is this: If it would take more thread for me to tie off and re-start elsewhere than it would to just jump across, then I jump across. This probably means I jump more than others do, but if I'm going to use the same or more thread to tie off, I can't be bothered to go to the hassle of doing so.Shogun wrote: 4 - how clean do you keep the back of the fabric? As I was doing it, I would generally work a color first, and sometimes I'd have to skip say 3-4 squares and come back, and it would make a lot of x's and ugly threads on the back. Am I better off just making the squares that are next to each other, then tying/looping the thread and cutting it off and then starting fresh 3-4 squares later? Does keeping it clean on the back really make a big difference, or is it more work than it's worth?
Generally speaking nobody but you is going to see the back, so how messy you want it is up to you. But you should be aware it is never going to look as good as the front. Ever. Even the tidiest of people have to occasionally jump one or two or go diagonally and so it always looks a little weird.5 - I've read about not tying it off on the back, but just looping it under some other threads. I have a few concerns about that - do threads not tend to come loose? It seems like they would, especially if you have to wash the thing to get all the wrinkles out. What I've done is taken the 2 strands I'm using and just made 2-3 simple knots. It also seems the looping of the thread makes the back look pretty ugly.
I always suggest not using knots, especially for cross stitch because not only does it look bad if you end up framing it when all the knots push the fabric out, but they have a tendency to pull through the holes of the Aida and therefore aren't terribly secure.
If you dislike the looping at the back, you can anchor them like you do with other embroidery-
Put a knot (ugh, I know but it'll get cut off) and pass your thread from front to back a number of squares over from where you want to start. Then stitch across the thread as you go. Cut off the knot when its secure or in your way.
I personally don't prefer this as it not only takes more thread and effort (and I am at heart exceedingly lazy), but it has the same issue that using knots at the back has- they occasionally jump through the hole in the Aida and you have to start all over again. It works better with other embroidery as you're not using fabric with giant holes in it.
