Let me introduce you to Caterpillar Green Yarns an artisan yarn company based on Vancouver Island, BC. It produces the most fabulous self striping yarn you will ever see.
Now I must tell you about purchasing from Caterpillar Green Yarns. When I first found them, of course I immediately went to the website. That's where I saw the Concrete and Tulip and knew I had to have that but it was marked SOLD OUT. Then I went to the next color SOLD OUT. Then the next SOLD OUT. Then I emailed the company. They gave me the date and the exact time they would have yarn available to sell. Being the absolutely compulsive person I am, I logged in on the minute. I got my two skeins of Concrete and Tulip and one skein each of Warm and Fuzzy and Olive Branch. About an hour later I went back to get another colorway that I thought I could not live without but it was already SOLD OUT. As a matter of fact pretty much everything was SOLD OUT. They did have the next date and exact time yarn would be available again. That happened to be Thursday, November 5 at 10:00 Pacific Time. They even had a little calculator which would give you what time that would be in your time zone. Well, for me it was 1:00. I impatiently waited until exactly 1:00 on Thursday, November 5. It was the craziest thing. I got my three colorways (I wish I would have purchased a couple of skeins of the sock yarn) then I watched each colorway sell out. It is the craziest thing! There is such a demand for this yarn.
