Would anyone out there who has done a paper circuits program with adhesive copper tape be willing to share where you found the tape at a decent price?  Need it for about 300-500 person event.  I&#39;m seeing some for $2.95 a roll (1/4 in width, 50 feet) but it doesn&#39;t have conductive adhesive and is pretty thin (.08 mm thick) and am wondering if it will work well enough to light up a 5mm led powered by a cr2032 coin cell battery?  I can&#39;t afford the over $10-20 dollars a roll I&#39;m seeing on other sites.<div><div><br></div>Thanks,<div>Kelaine Mish, MLIS</div><div>Kent District Library</div><div>East Grand Rapids branch</div><div><a href="mailto:Kmish@kdl.org">Kmish@kdl.org</a></div></div><br><br>-- <br>Galatians 5:22-6:10  (with some creative control)<br>The harvest of the Spirit is love, joy, peace, patience, kindness, goodness, fidelity, gentleness, and self-control.....so let us never tire of doing good, for if we do not slacken our efforts we shall in due time reap our harvest.  Therefore, as opportunity offers, let us work for the good of all....<br>
