It will take many months or years to be completed but I am sure that it worth it!

I use all leftover sock yarn scraps that I have had so far.

I don’t follow the instructions of two decreases in the center of the sts, instead I do a double decrease by slipping together 2 sts knitwise, knit the next one and pass the two slipped sts over last knit st removing them from right needle.
On the next row I knit all sts except the one in the center, which I purl. That’s why I CO odd number of sts (47 sts).
