Just do

But, do you see my problem? I really like to carry these 2 bottles with me. I’ve seen it is going to be over 30 degrees Celsius, so lots of water is needed. But these bottles don’t fit into the bag, and there is no way to attach them to it.

Do you see the strap on the side of the bag? That is certainly useful.

I made 2 holders for the bottles, with strips with velcro. So now I can carry a bottle on either side of the bag.

Perfect for the next couple of weeks! It is now after midnight, there is still a pile of laundry waiting for me to iron, there is some cleaning to be done and I have to pack. But then, tomorrow morning we are going to Italy. Ciao!!
