ReP-A-R-E (RePurposing, Alterations, Repairs and Embellishments) #5 is a no sew one, but has been really great for me so worth sharing I thought.
I have a lovely dark burgundy/oxblood leather bag which I started using again, but realised the existing handles were not quite long enough to have it over my shoulder. and when I went shopping it was rather in my way on my arm, as I prefer shoulder bags.
I added a plain silver key ring to each of two of the D rings holding the original handles, looped the belt through and knotted it. I now have a soft shoulder strap for the bag, which makes it much nicer to carry. If I change my mind in future I can remove the belt and key rings with no damage to the belt or the bag, but in the meantime I am using the bag and enjoying it!
Some sewing on the next one honest!
