Hi some more photos/examples/types if you want ideas:
I like this design, 2 sides of shelter and a ground sheet "MoD shelter sheet"(Basha)
This is a good design if you need all-round vision, but has little protection from the sides, so not good in wind. (each corner is supported by a stick) quite difficult to make quickly.
a cosy nook! the MoD basha, in a triangle shape is almost total protection(tree is one wall) and room to lie down.
a single hoop basha design, (on this thread I started
http://www.bushcraftuk.com/forum/showthread.php?t=56960&highlight=) can be made with natrual materials and requires no cordage! it's total protection from wind/rain, but it will be sweaty!
comparative sizes (note the trees as a measurement) MoD basha:
British Army 58" poncho:
German Army poncho:
MoD Basha, 2 mini poles, enough space for...3-4?
MoD Basha, 2 micro poles "tent" design:
MoD Basha/US army poncho comparison:
...And of course you can use them to be
Blatant!
