Library Finds and yarn sticker shock!

Well, I was quite pleased with the knitting books I found at the library today. I thought to work on something other than my fave baby sweaters and socks. I would love to knit a tank top or tee shirt. The prices of the suggested yarns are simply out of my budget at this time. A simple tank would run over $60 in yarn.
With cooler weather soon approaching, I had thoughts on mittens and hats, but not done up using the acrylic yarns I taught myself with last year.
So, are there affordable alternatives? The more expensive yarns are gorgeous to be sure, but I can't swing those prices right now... still have to work on getting the new home finished and furnished.
How depressing. I really wanted to do this tee from The Ultimate Knitted Tee, by Laura Militzer Bryant and Barry Klein (page 47). I guess I could try an acrylic version as a trial run until I can afford the better stuff.

Finishing a whole lot of nuthin'

Discovered I am not finishing many of the projects I've started this year. For one reason or another... incorrect guage (despite swatches), but mostly short attention span. I do enjoy having several projects OTN/OTH. I am knitting a sweater in the round while pedalling 10 miles (takes one hour) a day on the stationary bike.
There's a baby sweater from Leisure Arts Leaflet # 643 Book 3. "Webbed Set". I am doing this one in yellow and white for size NB/3mo. I work on this one in the wee hours of the mornings during my wake-up "me" time.
I have finished a few simple dishcloths. I guess I need to start finishing a few items so I can post more.
