I like to put my blocks together in quarters. You end up only having one, maybe two, long seam to sew. It is always easier to handle smaller sections at a time.

if the quilt is ten by ten blocks I will divide into four sections, each with 25 blocks ( 5x 5).

Sew each section and then sew the top two halves together, then the bottom two. Now you have two sections, a top and bottom. One seam across the middle finishes it.

peace

I either do like Ube Quilting and put them into quarters, or use horizontal rows, just because with a rectangular quilt the H rows are shorter than the vertical so less fabric to be handling.

I don't think so. Sometimes I also sew in quadrants or sections.

I generally sew in rows. When the rows are finished I sew them together in units of three or four rows to keep the size of the piece I'm working with more manageable. Once I have that done I'll sew those units together. That means I only have one seam where I'm working with the large quilt as a whole.

I also assemble the quilt in quarters. This way, you only have to sew 1 loooooong vertical and horizontal seam. I find it easier to match when working on shorter seam.

I sew in rows too. I use paper with letters and numbers: A1, A2 etc for the first row. Then B1-10 for the second. Always works for me.

It does not matter. I prefer to do shorter rows, so I usually sew my blocks together into horizontal rows, then sew those together.

I label rows and sew those first. Then I sew rows 1 to 2, 3 to 4, 5 to 6, 7 to 8 etc. Then I sew 1 & 2 to 3 & 4 etc. so I am only dealing with the whole quilt when I join the top and bottom halves. Hope that makes sense.

I always do rows also. It is just the way I prefer but I don't think it matters

I think most people sew in rows because that is how our brains work. The left to right is the way we scan and perceive things, so it makes a bit more sense (is easier) to process. But, it doesn't make it right or wrong to do it either way. Again, it is your quilt, your house, you get to decide what is more comfortable for you.
