We have always tried to make "The Three Muses" a friendly place where anything goes - a place for bloggers to post their lovely artwork and a place to make friends. Everyone is welcome and there is definitely no preference as to art styles whether they be mixed media, totally hand-made, digital, cards, stamping, etc. We truly value our regular participants.
The only rules we have are that entries should make some reference to the weekly theme and that our website should not be used for advertising. There is a notice to this effect on our blog.
Unfortunately, any entry which appears to contain product promotion (usually through multiple posting to large numbers of challenges) and/or does not cover the weekly theme will be deleted without discussion.
