I have to say the best part about working on smaller projects than 6' x 5' Afghans, has to be the frequent 'I'm nearly done!' buzzes. Most of my afghans took 2 years - mostly off, to be done. But I've gotten done more hats and scarves and mittens in the past couple months than I have ever done afghans.
It's also been challenging, after all garter stitch afghans you don't need to see to do right. I've gotten almost competent on dpns (which I didn't know existed 2 years ago). I've learned a lot more about patterns - though I have yet to follow one completely. And before the only patterns I've followed have been cross-stitch ones. (Which reminds me, I really should take out the long neglected Santa project.)
But here I am, 1:30 in the morning - working on finishing a hat - with a giddy smile that would make you think there is Apfelsnapps in my tea. :)
And now it's done.
