I wanted to use curtains that didnt require a rail system to support the top and bottom as this can interfere with the space inside the van. I therefore opted for some simple curtains that are velcro-ed in place when required.
Step 1: Buy the Materials
at least 5m of velro with stick hooks and sew loops. (~$50 in australia!)
Sewable material of your choice (we used a low weight poly cotton blend)
A sewing machine (ours was found on the side of the road).
about 2 hours per curtain (I also learnt to sew in this time)
