I have just noticed that I still haven't shown the halfbuckle wrap conversion, I made last year for my husband. I talked about it here.
I made it from a Hoppediz Panama wrap that I had bought on ebay.
The text on the headrest: shush, I'm sleeping!
Height and width of the panel can be adjusted.
Headrest is detachable (and I could make another, more suitable for myself, since this one says 'baby wearing dad')
The straps are upholstered on top (2cm foam) and can be spread further down.
