Notes

1. After the set-up row you will be working in the round. Read every line of the chart from right to left, starting at the bottom, working it twice per round (once for the front and once for the back).
2. Avoid tangling yarns by keeping the background colour yarn on your right and the pattern colour yarn on your left.
3. When there is one colour in a round work it on its own, without stranding another colour with it. 
4. When stranding floats across the back of your knitting ensure stitches on the RN are evenly spaced out and not bunched up. This will avoid the fabric puckering. 
5. f there are long stretches of one colour, catch floats (the other yarn) every 6 stitches - sometimes this will need to be more often, that is fine. 
6. Don't catch floats in the same place in adjacent rounds to avoid the float yarn showing through on the front of the knitting.
7. If there are a few rounds before a colour is used again (eg four rnds), do not break the yarn, but bring it up vertically (without pulling) and twist it after 2 or 3 unused rnds with one of the yarns in use. This will minimise the number of ends to weave in.
8. As the stitch count reduces on the shoulders (from Rnd 64), change to using dpns or your preferred technique for smaller circumferences to avoid stretching the knitting.
