If you do write a pattern for a specialty yarn, it's best to make sure that the yarn will be available for ease of purchase.
I recently made a hat and scarf set for my sister in law that deemed to be very popular, so I began to write a pattern for it, although the initial set I made was easy to make up, once I started writing the pattern for readily available yarn, I had to make many alterations to the original pattern. I knew that the specialty yarn was old stock and I was not able to recommend an alternative yarn for my readers to use. What made further difficulties for me was that I used a yarn ply I was not familiar with. You may be wondering why I did that. The reason being is that here in Australia , we have a nation wide department store that is now stocking Red Heart yarn! This was my first chance to use it in writing a pattern, this ply of yarn is universally available.
So I had lots of frogging and deleting/retyping text, this is all while I have a head cold too. What would have taken me 2 days at the most has become double that and all for the love of crochet.
This is the original crochet hat and scarf set, the buttons really set it off
I love the crocheted textures within the hat and scarf
The beginning crown of the hat, reminds me of an older style tupperware lid
I have 2 sizes almost completed with the Red Heart yarn
This is how I mapped out the pattern for the body of the hat pattern
