as long as your seams are not pulling apart on the ends and your tension seems fine it will probably be fine- you could shorten your stitch length a little bit-that may help are you pressing to one side or pressing your seams open? if you are pressing them open- changing that - pressing to the dark side- or to one side will keep the seams from showing...once it is all quilted & bound, it will more than likely not be noticable.
