Thanks Momto4 Hope this helps. I lose points too but if you prevent as much as possible then you don't feel so bad to have to say oh well and let a point or two go if you have done all you can to keep them in line!
I actually hate to do some of these steps but I force myself to as it makes such a differance in how your project turns out. This is definately my least favorite thing to do but it is necessary.
I can't tell you how many times I have had to go back and tear things out and fix a seam. (tighten) so a block is not leaning to the right or left and or a block is ruffling.
Hope these steps work for you!
