We have 99cents only or Dollar trees cheapy stores here in The USA that sell 21"x21" Bandanas in Every conceivable color,pattern,etc. for 99cents each.I can easily sew 4 together to obtain 42"x42" If I wanted one that large!As for Para-cord,If 7 strands are not enough for you,I have to ask",What purpose does one have in mind that would require more?"& The 11-strand type is double the price of 7-strand,I just don't see an advantage, short of actually having 11-strand in place of 7 supporting the risers on an M-8a floppy doing a HALO!
