Grab&Piece

So as I recently posted, I'm working on a scrap quilt in the 'grab & piece' method, and so far, so good. I'm using as much of each pull as I can in each block, before moving on to another. With the first block, which measured 15" x 21", I ended up with just a small pile of neutral strips, which I'll fold into the next pull, rather than return them to the basket.

The second block turned out much larger - 19" x 27" - and reminded me that I didn't have to take TOO big of a handful to make a reasonably sized block.

Block 3 was slightly smaller at 19" x 21". I've been surprised how much white was in my scrap basket!

As I've begun making these blocks, I've also made a few rules for myself:

1. Try to use up each scrap pull into a block, but if the block feels done before all the scraps are used, blend them in with the next scrap pull.
2. No purple, as I'd already been gathering that for a separate project.
3. Just use quilter's cotton; other substrates will be used elsewhere.

Here are my first three blocks up on the design wall. 

TBD what filler I might want or need later on. For now, I'm just making blocks. But let me know in the comments.... do you think a quilt like this is enhanced by added big swaths of color; or do you prefer just the chaotic scrappy blocks?
