Have you got the brioche bug yet? Wraparoche is an easy and very satisfying introduction to two-colour brioche. You can make it with two skeins of whatever you have on hand – as long as each skein is about 100g and about the same weight. The sample uses Wolff & Schafe Romulus (a really lovely, squishy Merino worsted!), but the pattern also includes instructions for fingering or sport weight, and a worksheet to figure out your numbers for any other gauge.
The pattern includes notes on how two-colour brioche is worked and how to read the instructions, plus photo tutorials on the special cast-on and cast-off techniques used.
