You could just mount some curtains down there?
Looks better that blinds as well imo
There's probably a very simple solution for this but to bump the post I have one of my insane DIY ideas:
Install the blinds you ordered upside down at the bottom of the window
Attach a hook (bent paperclip) to the "bottom" of the blinds using tape/piercing the material itself and threading it through
Attach some string horizontally across the window at the point you want the blinds to roll up to, accounting for how large the hook is. Using wads of sticky tack or nails depending on how much of a pathetic fucker your landlord is with regards to "muh property damage".
Then, you can unroll the blinds from below and hook them on the string.
lmao went to the PC to draw this set of german professional quality engineering diagrams (glowies now have my shitty artstyle RIP):
ShowShowThis "design" makes a few major assumptions, such as that the blinds do not have a locking mechanism where they need the power of gravity to roll out (just imagining worst case scenarios, ive never taken apart blinds before and i doubt they would)
Also assumes you have string/nails/tape on hand, what materials have you got?
There are accordion blinds that go both ways and can open top or bottom. They cost more than rollers.
But that’s not your question. And you already ordered rollers.Roller blinds stay in place with gravity. The rolling action works mechanically in any direction.
But how to keep it in place upside-down? If you can put holes in place, parallel hooks/nails/screws at the levels you want should work. The key being the dowel rod that runs through the shade would have to be wider than the screen.
And the description doesn’t necessarily make it clear if this is an outside or inside hang, as methods will differ. Places that sell them generally have a blindcutter that can be set for outside or inside and also trim the rod. Generally there isn’t a charge for this when purchasing, might have luck taking them to a store if they need a trim and getting a complimentary cut if they are too wide. Leave the dowel longer.
Another one I’ve seen is getting a decent suction cup hook and putting a bit of looped paradors or something on to put on the hook.
