Inktense Blocks by Derwent; Are They Permanent on Fabric?  

Thank you all for your continued support. It warms my heart!
I finally bought the Derwent Inktense blocks that have been on my wish list for awhile. Will they perform the way I imagine? Let's play with them and see.

I apologize for the quality of my videos. They look fine on my software but when I upload them to RU-vid they get blurry. I am not sure how to fix this. Any ideas are welcome.
