New way..

With the pouches on the shoulders, it can be awkward when the straps are thin.

The red elastic band with two clips on the end is actually used to clip winter-gloves on the manchettes of coats... But this is much more practical.

Here I used the safety-pin to put it on the elastic band and the straps... but since then I sewed pouches all the way at the end.. no more safetypins..
