Recently, 3" bidrectional tape has been used to cut costs, and foil tape helps out in a variety of applications. See the [[http://www.appropedia.org/Hexayurt_playa#The_Tape tape]] discussion for more.
#'''Mail Order 240 yards or less of 6" bidirectional filament tape''' such as [http://products3.3m.com/catalog/us/en001/manufacturing_industry/packaging/node_GSX56YFN5Kbe/root_GST1T4S9TCgv/vroot_GSS0K4MVF7ge/gvel_46CLPS2NRMgl/theme_us_packaging_3_0/command_AbcPageHandler/output_html 3M 8959] "Extreme Applications" packaging tape, 6" wide. AKA as "
T.R.U. FIL-835B/D." 6" is not a standard width, it usually costs around $30 plus shipping. 5" tape is perfectly good. For certain steps, you can use 3" which is half the price and a lot easier to work with. 3" tape for foil tape is ideal for sealing the panel edges during preparation--in fact, you can seal the edges with quite a few tapes. Foil tape has also proven nice for tape-sealing. If you are employing the "classic construction" approach, you will seal all panel edges prior to assembly: that step alone takes 132 yards of tape.
