Hello,

In "101 Ways TO Help Birds," by Laura Erickson it says: "never set out dryer
lint for nesting birds. although the soft fluffy lint feels suitable both to
us and to birds, after it gets wet and then dries, it becomes brittle and
crumbly and could cause a nest to fall apart." the book also says: "any type
of string or twine should be no longer than about six inches to prevent
possible strangling." that is on page 171 in case anyone is interested.

hope that helps.
