As several members design, we should be able to build up quite a nice library. Even if a design was conceived for a particular occasion, e.g. an anniversary sampler, you may still wish to share it for people to use with different names and dates.
So how do you go about posting in this thread?
1. Find out whether you hold the copyright to the design.
I cannot stress this too much! If you designed something from scratch you should be fine, but if you have any doubts (for example because you designed a sampler using existing designs from books or mags) please first post a message explaining the situation, and together we should be able to work out whether it is suitable for posting.
2. Turn your chart into a format that is accessible to everyone.
If you post your chart in the format of whichever stitch computer program you use, many members may not be able to use it. It's probably best to turn your chart into one or more image files such as JPGs and post them as pictures.
3. Give your posting an informative name.
Please don't call it 'new chart' or something like that -- if it's a chart of a goldfish in a bowl, call it Goldfish In A Bowl. Dull, I know

4. Add a colour key.
If you use floss numbers in your colour key, don't forget to say whether they're DMC or Anchor or any other type of thread. Of course it's also possible to use colour names such a Light Red and leave it to the user to choose their favourite brand.
5. If you wish, state limitations to use.
Perhaps you're happy for people to use your design as it is, but not for them to start changing colours or adapting the design. Perhaps you're happy for them to change whatever they like, but not for people to start kitting up your design and selling it.
There, I think that's probably all

I'll post a couple of my own charts later today to get the ball rolling. Enjoy!
