When I first got back into knitting a couple of years ago, I tried to make as many Christmas presents as possible. Since I had no life that Winter, I managed to make 2 scarves (which you can see here) and 2 cushions, both of which were stripy and used mostly the same wool (to cut on costs) but with a couple of differences (you can see the other cushion here). This cushion included pink as it was for my friend Fran and she likes pink. You can find the pattern here – there’s no point me typing it out and I think it might breach copyright or something.
I’m not sure if the colours are meant to match on the seams when you sew it all together, but my tension is always a bit off so mine didn’t but I don’t think it affects the look of the cushion at all.
Tip: As I said earlier, my tension is always a bit rubbish (i.e. looser than it should be) so I would buy the cushion pad after you’ve finished the knitting to make sure it will fit.
