...down the gradient rabbit hole...
The patterns each feature one of these beautiful yarns. Spectral is done in Miss Babs Yummy 2-Ply Toes in the colorway Pegasus, and Traliccio is done in the color way Ivy (looks like it missing from the website right now, but I'm sure if you emailed Melanie you could get it. She's nice like that).
The whole gradient thing is really interesting and there are so many ideas I have running around in my brain I've taken to carrying a notebook with me to get them down on paper. Look for some more designs using these beautiful yarns in the future!
And as I said, if you haven't had a chance to get any of them for yourself GO NOW!
