Love drawing by hand when I get time, learning to convert over to a digital media but have been working with Photoshop for years creating backgrounds and web design.
Many of the new celtic knotwork designs are available on clothing, coffee mugs, stickers, etc. on my TeePublic store. https://www.teepublic.com/user/the-knotty-works
Ordered a Picasso Tab XL Saturday and it arrived today. Loaded several (free) drawing apps and played around with Sketchbook but not as happy with the Android version. So for Ibis Paint X seems to work pretty well, though I have a lot to learn how to use it effectively.
