Mercerie is the French word for haberdashery, “dry goods” or a shop that carries notions, trims and/or fabrics. So if you’re reading this, it’s probably your kind of shop.
The blocks are simple - two "regular" four-patch squares and two "shaded" four-patch squares. Same size. While the shaded four-patch squares are easily pieced, Open Gate Monique's ruler makes them perfect - and perfectly easier. (I love that about the ruler - and her.) Finished size 33in x 33in.
