If Marshall Pass (off Highway 50 in southeastern Colorado) is not convenient to you, I can also recommend Ohio Creek road from north of Gunnison to Crested Butte. Nearer to Denver, I hear that Guanella Pass is pretty, but I'm not sure how the color is there this year. It's on my list of places to go.
Meanwhile on my list of yarn to knit is this gorgeous pile I recently ordered.
It's funny how the golds, browns, and greens echo the fall colors. I ordered this a few weeks ago, though, when I went on a spending spree with some of my paypal-pattern funds. It's primarily Enya sock yarn from Saffron Dye Works. I haven't knit it yet, just put it in my "to-be-wound" box. However, I'm very pleased with the look and feel of it so far. The colors look as great in person as they did on line. I'm letting myself dream of a shawl combining colors from the three leftmost hanks, but not ruling out just knitting pretty socks. The lavender hank is laceweight, just enough for a small shawl. I can't say why I bought it exactly, but it and the sale-priced sock yarn hank on the right put this order into the free shipping category. I think I'll go back to Saffron Dye Works whenever I want a treat.
I'm afraid that most of my yarn purchases are either treats or bargains. I buy yarn because I like the color, the texture or the price. Lately, I've thought more about planning my purchases. Today, as I held a single yellow leaf in my hand, I thought it would be fun, and perhaps a little smart, to take a handful of leaves on my next yarn shop visit.Aspen-yoke sweater. It would be fun to knit in yarn that matched the actual yellows, reds and golds of the leaves, with a dark green for contrast. Uh-oh, I feel a stranded knitting urge coming on. I need to finish that lace shawl first, though. At least it's gold.
