I teach a "Silk screem Workshop" in a high school and we use a blog. I put
there about the process and the activities during the class. There are many
pictures and videos but it's in Spanish. because, I live in Mendoza,
Argentina. We speak in Spanish. :)
You can visit my blogs if you like :)

They can review de process and read the manual and we have a chat, then, we
can talk about the doubt.
I think it's very useful, and the students enjoy to watch the picture.
