Petra Socks
The Petra socks are inspired by the beautiful stone pathways in Pompeii and are a collaboration with the incredible Woollentwine Fiberstudio! This is a pattern for fingering-weight mid-calf socks with beautiful textured waffle stitch. There are a few intermediate techniques, including Kitchener stitch.
For this pattern, you will need one 100g/410 yard skein of main fingering-weight yarn. For needles, you will need a set of 2.25 mm (US size 1) DPNs, and a needle to weave in ends.
This size breakdown is as follows (as measured around the widest part of the foot--usually the ball of the foot)
Size 1: 7in
Size 2: 8in
Size 3: 9in
Size 4: 10in
If you need a size that is not listed (such as for 6in or 12in) please email me! I am happy to grade it for you!
These socks are designed to be a bit snug at first (about 10% negative ease). Socks stretch as you wear them! If you are knitting with superwash and intend on wearing these socks a lot, keep in mind that superwash can stretch up to two sizes!
If there is a difference of more than three inches between your foot circumference and your ankle circumference, I recommend choosing the size that corresponds to the biggest number.
If your heel is wide, you have a low instep, or you have a wider calf, you may want to knit the cuff and leg a size larger and then decrease down to the stitches for the smaller size foot. For example, if you want the cuff of a size 3 sock but the foot of a size 2 sock, cast on the required number of stitches stitches, knit the size 3 sock until the gusset decreases after the heel turn, and then decrease to the required number of stitches (the amount stated for the size 2 sock)!
If you have a high instep, I recommend knitting the heel flap .5-1 inch longer than the pattern calls for. You will then pick up more stitches along the edge of the heel flap and then do more instep decreases to get to the called-for number of stitches!
If you have any questions about the pattern you are welcome to email me at sundaymorningknits@gmail.com!
