This was made with alpacca, rapunzel, and a wool slub. Size 17 needles, 91 stitches across (garter stitch) and i just alternated each row with the different yarns. It's about 6 feet long, and I would say about 4 feet across! It took over 75 hours to knit, but the different textures of yarn kept it interesting!
Here it is all stretched out (some of it is behind the couch):
And here it is resting on its chair:
