Need to once again publicly shame myself for not seeing the freaking obvious.
My husband and I are renting our apartment. Our bedroom faces another apartment building, and our vertical blinds have all the blockout qualities of tissue paper.
Last weekend our neighbours were on their balcony until the early hours of the morning, and the lights shone straight in our bedroom window.
Brainwave number one came on Sunday morning when I went online and got a quote for blockout blinds for the window. $150 to sleep? Sold! We've been in the apartment four years. I was kicking myself for not doing something about this earlier.
(I didn't purchase anything, but we agreed to get the local blind store to come assess the window.)
Brainwave number two came, oh, about three minutes ago when a little voice in my head said, 'Duh, eBay, second-hand verticals'.
I had a quick search on my phone, found dozens of options within 10kms of home, all for <$30. Texted my mum, she confirmed that she can hem them if I can't get the right length. And I know I can wash them at home.
(When we moved into our current place the verticals were very grubby. I pulled them down, soaked them in Napisan in the bath and hung them back up spotless.)
I really doubt my own mental capabilities when it took so long for that to occur to me!
