I bought 6m of khaki coloured muslin from a fabric shop online and it arrived today, I have put DD in it in a front cross carry, a rucksack carry and a hip carry and it is FAB!
It's virtually seethrough so very, very light and breathable but as it is 40 inches wide there is more material to hold her so I am not worried about strength.
And it folds up tiny!
No comments needed, I am just feeling very smug, might have to go and get some more in every colour!
