Whew. Well first of all, thank you both. At least I’m not crazy! 
I did check her pattern for the abbreviation descriptions first thing, no luck for SK. I checked all over the web and only found that SK meant Skip stitch.
The woman who created the pattern is Claire Garland.
The pattern is called the Heidi Dress & is made to go with her Pixie Moon Doll. (Which I had no issues with). I think she may even have a book out. I’m not sure. I unfortunately don’t have a link to the pattern.
There is indeed different colors of yarn. The main color, the trim (T) color and the Detail (I) color. The weight is DK.
Hmm…maybe I can try contacting her through her Etsy account. The last time I tried contacting a popular knitter I received no response. So I guess I felt a bit discouraged on that count. I’ll try again. Perhaps Claire is more generous in that regard! One can hope. I’ll let you know how it goes.
In the meantime, if you do indeed think of anything I’m all ears!
Thank you very much.
