Getting samples ready

I mentioned before that i will be contributing to the Sampler next month. I am busy getting sample packs ready with vintage image magnets. They look so pretty all stacked up on my desk, there is a part of me that just wants to keep them all! But how many magnets does one person really need? (i must say since i moved to the US i am very happy with the large refrigerators they have here, so much space to put magnets on!!)
