This "love" tape could be mixed with selvages in a selvage quilt, don't you think? I found it at The Crafterie. It sells for $6.50 for 3 meters. All kinds of ribbons could be added to selvage quilts. Black and white would be nice. Have you used ribbons with selvages?
Here's what my sister Lynne in Vermont had to say about the dark plaid block:
I like the new dark tartan plaid square. I pictured something way more subtle: navy background; stripes of dark green, deep red, maybe even black. And very, very narrow stripes of brights/lights: yellow or orange. But the black and white print? That was a shocker! Karen, you're always throwing a new twist on things! I'm looking forward to seeing your new plaid quilt.
