Stuff that you can get from non modeling sources.

[Pete J.]

Here is a very handy set you can get from Cabelas outdoor sporting goods.  It is an assortment of lead wire used for tying flys and other fishing  applications.  It is really good for hoses, wires and tubing.  A simple pull on each end with pliers and it will straighten and it bend very easily.  If you clean it with a little acetone or lacquer thinner and it will hold paint very nicely.  This is a cheap alternative to the stuff sold in little packages in modeling shops. For the worry warts, yes it is true lead and in sufficient quantity will cause you harm, but it is really hard to get enough in your system from handling this small amount without wadding it up and chewing on it on a daily basis.  

Here is the website. https://www.cabelas.com/catalog/product.jsp?productId=744541&type=product&WT.z_btnclk=YMAL-744541&WT.z_pg_ref=prd744646

I've found all sorts of useful stuff in the jewelry making section of Hobby Lobby.  Thin wire, chain and lots more.

Remarkable that the Cabela ultra wire assortment comes in colors, is copper and comes in sizes equivalent to .006" and .012". 

Thanks Pete for the link.

dollar/pound shop make up sections can be good for weathering stuff and nail varnish in some unusual colours. The suede effect nail stuff is very fine flocking

Re-usable basket style coffee filters make for great fine screen material.

Some of  those mylar party balloons come attached to plastic tubes. The pieces of one that I have are styrene. The tubing is roughly 3/16", in diameter. Turns out it's the perfect size for the cylinders on my four cylinder Flattie!
