I have just published my first online class on SkillShare, called "Abstract Collage: Creating Compositions with Tissue Paper". Take a look here, and get two months of access to all of SkillShare's video tutorials free. Following the SkillShare format, the class contains ten short video lessons in 43 minutes. You can post your work on the site, ask questions, see other's work, etc.
I take you through the process of painting/staining tissue paper, cutting out the shapes, and playing with arrangement, all in the service of exploring abstract composition. Check it out! And let me know what you think. This is a new platform for me for teaching, though I have been a member of Skillshare as a learner for over a year.
