How about a glue runner, like the kind used in scrapbooking? http://www.acmoore.com/p-60312-perma...875-yards.aspx http://shop.hobbylobby.com/products/e-z-runner-574905/
Mono and Elmer's are other name brands.
Here's one that must be a non-name brand (I never heard of it, anyway
) because it's so much cheaper than the others: http://shop.hobbylobby.com/products/...artmentId=5343
Just make sure it says it's permanent, and not removable.
