My annual Halloween party is vampire themed this year. My invitation is gonna be a vial of blood (fake of course) with an invitation"card" attached to it with the pertinent info. Problem is, I can't seem to find any vials. All I have found so far are the ones at Party City for shots with no lids that I bought cork tops for. Unfortunately the vials are colored (orange, black & red) and the blood won't look cool in them. I'm afraid my guests will have to open it up just to see what's in it. I think the effect would be much better with clear vials. Oriental Trading carries some but they have red, blue lids. Not exactly Halloweeny. Any ideas where I could get some? I like to send my invites early so I'm running low on time.
