nice job champ, i made a sweet one but the missis chucked it when we moved (not happy)
ive got a few things that may be handy to potential yowie suite makers.
the best is a dvd i have called "the hidden advantage" its about 40 mins long and this fella takes you through it step by step, then i have a few books and tid bits from the net.
but heres a few pointers for anyone considering making one.
1, as balty said hot glue( the type ya nan has for arts and crafts) was often used by actual sniper teams to make ghillies.(start from the bottom and work up to get an over laying effect)
or
2, is to use a cheap hamok(spelling) bout $10 from aussie disposals. you cut a piece the shape of the back of your BDU and saw it on at the corners, then you simply tie your hessian through the loops in the hamok material. real quick to make and allows you to add foliage from whatever area your in at any one time.
hope that helps
