I chose a pattern from Patons book 1253- Zhivago Kids - a simple cable.
It has been a great knitting project. I find cable quite soothing and requiring just enough concentration to prevent the knitting from being on automatic pilot.
This is the first time I have tried plastic cable needles. I tried both the hooked ones and the 'kinked' ones. I settled on the 'kinked' ones as a bit easier to manipulate. I really like the little ridges in the plastic that prevent them falling off the stitches - quite an improvement on the straight metal ones I have always used.
I needed less than 100 grams of the additional 400 I bought, so while using up 300 grams I had in hand, I have created another 350 grams or so of yarn for another project!
My habit of making children's garments a size larger than their age paid off in this case.
