hi all...

i'm making a duvet cover for my boyfriend for christmas with stenciled pictures on various fabric squares, and someone on here suggested that i do it in 12x12" squares sewn together in rows and attach them together that way. which makes sense.
i'm doing the horizontal rows first but so far i've only done one... i'm just wondering before i go any futher, i know that my measurements probably aren't going to be dead on, since this fabric moves a lot and it was hard to do anything precise enough, so is there a trick to getting the seams to match up when i sew it all together in the vertical rows? i'm terrified that they're not going to match and look horrible. is there something i should know about the process, or is it a case of just taking one square at a time and resewing the seams slightly to adjust them if need be (the thought of which makes me want to cry)?
i just got my sewing machine, so this is the biggest project i've ever attempted. oi.

(sorry for the text-only post, my scanner isn't working today :\)

thanks for any suggestions :)
