I have created my own patterns since I started knitting as a child. I'm not sure I can even say that, everything I made was mostly improvised. It was easier for me do that than trying to follow a design. Other knitters inspire me though. I love lots of patterns. I only use them as a starting point, to create my own.
Though some of my patterns have been published in Knitcircus Magazine a few years ago, I am still only a weekend knitter. However, I try to write down some of my patterns. I also like to share them, it's nice to see others knit something based on my patterns.
Sometimes I blog about my knitting projects at www.rékaknits.com
