Thank you! Having tried for over an hour previously, experimenting with various tips found on this forum and elsewhere on the internet, all without success, your post here including the video finally helped me find a solution, or at least inspired me to invent my own. The size of my small travel umbrella (154g with a very short shaft) and the design of my backpack are such that none of the commonly used techniques work. But now I realise that the key really is to have the canopy pressing against the top of my head, which in fact helps stabilise the umbrella. In my case, putting the shaft over the shoulder strap and attaching it there does not work at all. Instead, the shaft has to be attached to the side of the shoulder strap and tucked slightly under the strap, and held in place (I have no cord/lock for this purpose but my anti-nausea wrist strap does the trick). And viola! I don't even need to use the handle on my backpack at all. The only question now is whether it actually feels comfortable when I am walking with an umbrella pressing against my head, but I will find out.
