I've done both ways. As long as all your blocks are the same size it should
be ok. I usually take pics of my final design (just in case) and put little
stickers (I use blue painters tape) on every block. Mark A1 to A10 for 1st
row, then B1 to B10 for second row, etc. I put all my labels horizontally so I
will know in which direction they go. It's easy to twist things around when
you are at the sewing machine. :wink: Then I go to town. :-D
