Many times I get the question, "Did you use a pattern for that hat?" Each time I answer, "No". I never use patterns whenever I design my hats. Each one comes out on its own.
I spend more time enjoying the personal exploration of new creations than repeating the garment. I want to create each lump and bump, my own sequence of cable stitches. I want to be the first to create this sequence!
Once you mass-produce the item, it loses a sense of authenticity. Unless you were to personally request me to reproduce the item with a different yarn...such different shapes and swirls, of different textures and sizes. Take my pink flower hat for instance. The pink thinner yarn has a different effect than the velvety thicker yarn. The rose is stumpier and the rows of rose swirls get higher and higher. Wow! I guess maybe it wouldn't be much mass production anymore!
Take patterns on the other hand. There was an original designer before you ever came along. Following patterns are for the novice...one who has repeated the original pattern. The originally paid designer has profited. Be careful about copyright laws!
There is nothing wrong with following a pattern, but it goes only so far. Tweak it and twist it. Voila! It's your own design. This explains why authenticity has a nice name.
