[11.23] Overlays
(i) How do I keep them in place on the board?
A common solution is to use plastic page protectors (like the ones you protect your ASLRB pages with) and store them alphabetically in a ring folder. Small overlays can be kept in the plastic pages used to store card collections. When actually using overlays, there are many solutions. Many people recommend rubber cement, which will stick to the boards but peel off harmlessly when no longer needed. Don't confuse this with normal glue!
Other solutions include clear plexiglass overlays to hold the overlays in place (also helps to protect the boards). "Blue Tak" (that's the Australian product name; there are equivalents in most countries), the blue sticky stuff used to hang posters on the wall, will work fine in small amounts, but note that it has a tendency to leave a stain where it has been applied. Some people like to use draftsman's tape -- a type of clear adhesive tape that's designed to peel off easily without damaging the material underneath.
(ii) Where can I find a particular overlay?
