Purple knitting bag - Knitting olympics!

We've decided at the last minute to enter the knitting Olympics! Bradley is making me some mittens, in beautiful colours: orange, pinks and red, and I'm going to make a purple knitting bag. It's the same one that Sarah from our stitch n' bitch made that I posted about earlier. The pattern came from retroknits.com, but I can't find the site anymore, it seems to have disappeared.

I'm making a few small changes to the pattern, it's a different yarn so the size might be slightly different, and it calls for 200 grams and I only have 150, so it will be a little shorter. Also, I have bamboo handles, so they will attach a little differently. I'm not sure yet about the lining, the best thing I have right now is the fabric I use for the photograph, which has some purple in in it, but I may pick something else up later on.

The challenge is having the patience to follow a pattern, plus using two new stitches: butterfly blocks and sock heel stitch. It actually took me a while to figure out the sock heel stitch, I think it's that you have to bring the yarn to the front when you pass over the stitch (sl1). The first time I tried it the stitch looked like little waves, but then I think I figured it out. The other challenge is that it's also quite fine, I'm using size 4 needles.

I just found out I missed the midnight deadline...I emailed in case we can get added later on. After all we may be the only mixed doubles team!

p.s. update on the sock heel stitch - after the tip from Sarah (in the comments) I was going a little crazy trying to figure out what I was doing wrong because it still looked wonky. In the pattern you're knitting in the round so it said to knit every second row. But I just realized I was doing a test swatch on straight needles and on straight needles you perl every second row not knit! I had a weird version worked out that looked similar but was a lot more trouble plus not quite right. So thanks Sarah!!
