Years ago I took a City and Guilds course on P & Q and to organise all the examples we had to make I started using hard backed ring binders. Since then I have added to these and as they are each designated for quilting; patchwork; applique' and miscellaneous it has helped enormously. I teach classes and run two groups and so can usually find a pattern for anyone. In fact they all know my usual reaction to a new pattern is "Can I have a copy".
