If you want to submit a deviation to the group's gallery, your deviation must be:
a cross stitch project of any kind
How do you submit a deviation?
That's quite simple.
Firstly become a member of the group!
Secondly, you go to the gallery section and choose the right gallery for your cross stitch art. Then you click the "Submit to this gallery" button and there you can choose between "submitting a new deviation" or "Contribute an excisting deviation".
Your deviation will be submitted once the administrator approves it is in the right gallery. If it happens to be the case it gets not submitted, you'll get a message stating in which gallery you should submit it to.
