The MESH I used is the rain gutter leaf blocking metal mesh... a strip 
of it is about 2 feet long, by 6 to 8 inches wide, and comes in silver, 
and some colors.  cost is about $2.12 after taxes.

It is expanded aluminum, sold in all the hardware stores, and  I cut it 
with  those cheap stainless steel $1 scissors, from Dollar Tree next to 
Publix, in Butler Plaza, at Howell Branch Road and Semoran...
