A delicious dilemma

Block 5 is  was coming along nicely, but on Monday I had the chance to visit Bendigo Woollen Mills, and bought an assortment of purple-ish wools for a new cardigan. Five colours, perfect for a six row rolling repeat. This cardie will be worked side-to-side, starting at the centre back.

Spent most of Tuesday setting it up, and was pleased with it, until I discovered that I had some more purple wool stashed away.

Four 50g balls of lovely, deep, dark purple. What to do?
I could use it for bands on the cardie,but it's rather loosely spun, and probably not durable enough.
Add it to the mix? Substitute it for one of the other colours?

This is how it looks with the new colour added in - not sure if I like it?

Oh, and yesterday I just happened to be in our new local wool shop, and I just happened to fall in love with

this ball of Noro sock yarn, which will make a gorgeous shawlette, methinks...

Block 5 is calling me, and as soon as I get these crochet projects set up for car trips/TV watching/coffee outings, I WILL get back to it!
