The test block is totally unrelated to the HSTs and borders. It's just a tryout of an idea and a method, and it didn't work too well: wrong value contrast, disproportionate borders, and awkward finished size (10-3/4"). I used only scraps and leftover pieces, which explains the poor fabric selection. At least that's my excuse. :-)
