I was scared of sweaters, too. But now I see it's more endurance than anything, especially if you do a stockinette stitch sweater like me. :nails:
I started my first sweater this summer. It's To Dye For from SnB and is very, very easy--or it would have been, if I hadn't changed the gauge. I am doing it in a smaller gauge and learned a lot about gauge, measuring, etc. because of this. The algebra involved in calculating the frequency of the sleeve increases and decreases wasn't fun. I could hardly pass basic algebra 20 years ago. I've done the back and 1/2 a sleeve but have put it aside right now to make a present for my mother. It would have been so much easier to just follow the pattern, to have gotten the same yarn and needles. But the actual knitting is simple and nothing to be afraid of.
I also know nothing about seaming, but have been studying up on it for when the big day finally arrives. I didn't spend a lot on the yarn in case it does turn out to be a complete embarrassment. But it's my first and I am not going to let that bother me. I'll just wear it around the house if that's what happens!!
Well, anyway, most knitting instruction books have a section on seaming and how to choose the best type of seam for whatever it is you are trying to do. That's what I've been studying. I have to go now, but will post some links on seaming for you later.
