I always have incense burning or an essential oil diffuser going. My favourites are Sandalwood and Patchouli. Maybe this is a left over thing from my hippie days, but these fragrances always seem to be able to stimulate and calm at the same time.
Pattern. I love it. I can't seem to help it; it must be included in some way in everything I make. Often the quickest and easiest way is to apply it with stamps and stencils, but it can come from collaged paper, fabric, hand drawn and printed in many different ways.
Collage and image transfer are my 2 favourite techniques, and art basics Soft Matte Gel is perfect for both. It lives on my desk and I use it every day. Also art alchemy Sparks Acrylic Paint has become a new favourite medium that now seems to find a place in just about everything I make. I love it's thick consistency and richness of shine. ( Oops, I think I just included a sixth object )
