I usually use the Tyvek envelopes. I don't have the photo available, but you wouldn't believe what those envelopes can withstand. I had swapped a bunch of 12" blocks. When they were sent back they were in a ziploc freezer bag (thank goodness) inside the Tyvek envelope. It looked like somebody had dropped the envelope and about 15 semis had driven over it. The bag was torn and taped back together - do you know how hard it is to tear Tyvek? However, the fabrics were okay.
