Plaid, a block found in the perpetual calendar, 365 Quilt Blocks a Year by Nancy Martin, is drafted from a 5 x 5 grid.
It can also be found as #1827 in BlockBase.
Plaid looks like this when set side-by-side (a straight set):

Sashing and cornerstones added:
Another color shift on the Plaid block in the center of the quilt, plus the addition of an alternate block and a plain block:
If I were to make the above quilt, I might redraw the alternate crossing block so that the seams match the Plaid block.
I thought I was gonna be bored with this block. Turns out that I was wrong! There are more Plaid designs to play with in my Electric Quilt file.

What wonderful ideas! I, too, really like the slashing and cornerstone versions. They really “pop”. Thanks for showing us these. 🙂
