Mom's socks were knit with Cascade Heritage using a pattern from Around the World in Knitted Socks by Stephanie Van Der Linder, It's Tea Time. The only modification I made was to make a slip-stitch heel flap rather than continuing the pattern on said flap; I've found that whenever I do that, the socks tend to spring a hole rather quickly, so I'd rather sacrifice a little style for a heel that is extra sturdy.
The other pair of socks which haven't been shared on this blog were knit for my grandfather. He has really large feet and prefers basic stuff, so I freestyled a pattern that was interesting for me to knit that I hope he'll enjoy wearing. They're made out of sport weight Malabrigo Arroyo, which I picked for its superwash qualities along with the pretty color choices. These socks were my 400th project on Ravelry and will be released in 2013 as a new design, just as soon as I can find the time to get everything written up, formatted, and edited. Consider this a sneak peek!
