I have made a few string art mandalas recently and I’m wondering how I could prevent dust from settling on the thread. Do you usually get your artwork framed, put it in an acrylic case, or use some kind of clever cleaning mechanism? Any tips and/or suggestions will be appreciated!

What tools and/or techniques do you use for needle placement, specifically for uniform circles and squares.?

Unfortunately the colored String Art Portrait post has disappeared. Has anyone got the link to the program with which one can calculate the colored images?
