I find they stitch together just fine... and you won't NOTICE it much at all in the finished bit.
I KNOW, my hubby cut my hexies... and he SLID the ruler a little while cutting and thought it wouldn't make the diff so I just went.. " shrug" .. by the time I noticed.. it was too late and it was ALL GOOD.
BTW...it's the love you put into in the end that makes the diff
and it's relaxing..by the time you iron and quilt them - the little and I mean little tiny imperfection won't even be noticed by anyone but you. And personally. I'm not that much of an imperfectionist to get upset over it. Seriously my quilt turned out more than ok...
... she is loverly thus far.. ( queen size and still piecing on her).. lol. You can notice things if YOU ARE LOOKING with a MAGNIFYING GLASS and are perhaps going to a quilt show.. which I'm not!
. My advice is love the process and have fun. Breathe, relax and smile... cut the next ones and do the same. Keep going and love your quilt.
Much care, moi... ( Your quilt looks like it's gonna be one happy... guilt!).
