Taking good photographs of cross stitch is useful it you intend to record copies of your work. This can make a great archive to look back on and also remind you of work that you have done. Taking good quality pictures is also useful if you intend to send examples of your work to magazines.
Sending examples of your work to magazines can be a great way to let people know what you are working on. Many magazines encourage letters and photos from readers. An interesting development that has grown in popularity over the last couple of years, is the number of magazines that also have interactive websites. This means that they have discussion boards and forums and encourage readers to communicate both with the magazine team and also with the reader community. This is a useful facility for people looking to exchange news and views with like minded people.
