She is ( gasp) a new quilter, if I am reading the blog correctly. She is also a proponent of creative common (copy left! cracking up, as opposed to copy right) and I think creative commons is a powerful idea. I hope it catches on.
She calls her un-vented technique traplique, and if you read back in her blog, explains how she came up with it. I did that on my Houses at Night quilt, for the moon.
