They said I couldn’t sew with fishing line!
A pull-down shade cloth is fairly simple to make when using a kit ( https://www.bunnings.com.au/coolaroo-roll-up-blind-kit_p3301518 ).
The only issue comes from sewing the pocket for the dowel at the bottom for weight. I thought about many different options, then it hit me, fishing line.
I wasn’t about to sew by hand, so I got out the sewing machine and filled a bobbin with fishing line.
It was actually relatively easy to sew it, but I did break one needle.
