We looked at roller blinds for our balcony and ONE was costed out at around £100 fitted.
So last week we went to the market in Akbuk and bought a green plastic kitchen type rug for £8, folded the first couple of inches over lengthwise, threaded a line through it, drilled a couple of holes in the wall, inserted 2 hooks and simples, one blind. The next day fitted two lines to the bottom of the blind, looped them over the existing hooks and now we have a blind that rolls up as well. again SIMPLES.
Pop round and have a look
