Preserving your blood for spellcraft

For those of us who are weenies when it comes to shedding a little drop of blood for use in a spell here's a good solution I use myself:-Next time you shed blood, make sure to collect a little extra on a tea plate and spread it thin on the plate so that it can dry completely out well.-Once the blood is completely dry, use a razor blade to scrape the blood off of the plate into a fine powder.-When all of the blood is scraped off of the plate, carefully tap the powdered contents onto a piece of waxpaper, or regular paper, now roll the paper into a funnel shape, so you can easily funnel this collection into a tiny jar for future use.Now when you need blood for a spellworking, then you can use the tiniest amount anytime you want by just replenishing your collection every now and then.
