Quilt top with different "bulkiness" due to piecing density
 

I'll try to be clearer:o.

What are the implications (if any) if you have a quilt top where some areas are made up of many small pieces, and some areas are just big pieces of fabric? The heavily pieced areas will be thicker and bulkier due to the seam allowance. Will the quilt feel unbalanced?
I am looking at a scrappy string star quilt design (in particular Bonnie Hunter's), and I am wondering if the corners/sides would feel drastically different from the center?
Any experience in this? Thanks.

I've never noticed any difference.

I've never made a quilt like that, but I wouldn't think it would make any difference once it's quilted.

Press the daylight out of your seams as you go. I thought I would have that when doing my first bargello. Did not have any problem with it.

There shouldn't be a problem. For example, a pieced block alternated with a snowball or plain block is used lots of times in quilts. I agree-press the seams extra flat in the pieced block. I'm guessing (not a good thing LOL) that if the plain block does feel too"thin" you could use an extra piece of batting under that block. Does that make sense????

Haven't ever noticed this once it is quilted.
