FreeSpirit recently introduced a collection of basic/tonal/blender prints to join their Designer Solids. The basics are more modern than typical blender prints — there are dots, houndstooth, scribbles (called Twine), and pebbles (called Insincts), as well as a few others. I like the paint metaphor they used for the display, and the wonderful color wheel quilts.
There are now 100 Designer Solids, meant to coordinate with their designer’s prints. I don’t know if you can buy a sample card anywhere, but I’ll try to find out.
These color cards of Kaffe Fassett classics (yarn dyed stripes and classic prints) were also irresistible.
