Over-Sized Four/Eight Grid Sampler Blocks

Fabric: Shelburne Falls by Denyse Schmidt

X-Quartet

I started working on a new sampler quilt. The blocks are based on blocks from Judy Hopkin's 501 Rotary-Cut Quilt Blocks. My plan is to make between 12 to 16 blocks and end up with a queen-sized sampler quilt.  In order to make a quilt this large with a relatively modest number of blocks, I'm super-sizing the blocks I'm using to 16 inches. Anything beyond simple math befuddles me, so I stuck to 4 and 8-grid blocks, because they translate easily into 16-inch blocks.

So this is the first block, X-Quartet. I'm using Denyse Schmidt's Shelburne Falls, and I've roughly calculated needing 10-12 fat quarters, plus about 2.5-3 yards of a background solid, for all the blocks. I haven't decided about the sashing and border(s) yet, but I have a rough idea of what I want to do. But I still need to do the math (ugh) to figure out yardages. 

If you are interested in directions for the block, I've created a PDF with fabric requirements and cutting and piecing instructions.  You can download the PDF here.
