is the quilt all basted together? you may need to add more basting- if it is not enough to hold everything evenly- are you trying to tie it in a quilt frame? can you see underneith as you stitch your ties? ---if the X's look good i would think once the ties are tied being (off) a little bit will not really be very noticable....maybe show us pics of the problem...and don't be too hard on yourself---none of us are perfect.
