I’m certain I’m late to the game here, but I’ve just discovered double knitting!! My personal preference for mittens and fingerless gloves is flat knitting, seaming up after. What I wasn’t a fan of was one at a time and risking tension issues. Now having both going at the same time has solved my problem, consistent tension through out both items, brilliant!!
Also, let’s talk about Caron Cakes. Love them for these! Just let the yarn change at its own pace. No two are alike. I made a whole bunch of each, dropped them into bins and let the family pick which ever two struck their fancy. Guaranteed to “match” color family and yet have some character and quirk, plus such fun watching them all dig and fight over ones they wanted! Theses are the sets my daughter picked out.
