You typically want to collect wet blood with a cotton swab and allow the swab to dry completely before placing it inside a non airtight container. (Most cotton swabs in a CSI's kit will have a small hole in which to place the swab for drying, and will also double as a carrying case). For blood that has already dried, you can scrape a sample into a pharmecutical fold or into coin collector's envelope (a small 1 inch by 1 inch manilla envelope). The point is to allow the sample to dry and breathe so that mold does not grow on the sample, thereby destroying the sample. The point of ALL evidence collection and preservation techniques is so that when the case goes to trial in about 9 years, every piece of evidence presented is exactly the same as when it was collected.
