Amount X: 2 times the height of each window added together
Amount Y: width of each window added together
Size Z: our construction was +- 4 cm deep (but this also depends on the metal tape you’re using), so you’ll need to make sure your L brackets together with your window can accommodate that depth.
Our window was +- 2.5 – 3 cm deep and we used 2.5 x 2.5 cm L brackets which worked fine. If you have deeper window you can make do with less.
DIY built-in magnetic blinds
Measure the window width and cut the SCHOTTIS to size per instruction with the utility knife. Make sure the blind has a couple of millimeters of space on each side.
Now cut the metal (in our case the white one) and magnet tape (black) to the same size as the SCHOTTIS blind. Our material could be cut with scissors.
Cut the clips designed to hold the blind in a T-shape so that we can use them as handles, as per the photo below.
Now we want to secure the metal band and the handles on the blind.
Make sure that the grey side (front) is facing you and the glossy side (back) is facing away from you, otherwise your handle will end up on the wrong side.
Remove the paper tape from the blind and stick the handles on the blind roughly the same distance from the side.
Now remove the paper tape from the metal tape and stick it on top. Make sure that the backsides align with each other. It helps to do it with two persons.
Great, you now have a handle.
Fix and install magnetic blinds
On the bottom of the blind, install the Velcro as per the instruction. (I cut each piece in half).
Wipe the window with alcohol so everything will stick better. At the top of the window, place the magnet tape. (Press hard!).
At the bottom of the window, install the blind using the Velcro per the instructions.
Enclosing the magnetic blinds for the built-in look
Take the L-trim and cut them to size (height of the window). You’ll need one for the left and right edge of each window.
Sand the cut edges so they’re smooth.
Now, with two persons, figure out how much extra room your blind needs by holding the trim in the window while the blind is down. Test by opening the blind and mark with a pencil.
Measure the depth the blind needs on the L-trim and mark along the entire length.
Wipe the L-trim with alcohol and paste the double sided tape along the marked line.
In our case, we had some extra tape that we needed to cut away, since our double sided tape was a bit too wide.
Now, your L-trim should be ready for sticking.
Remove the blind from the window and with two persons, paste the trim in the window (make sure that the tape aligns with the front of the window).
Reinstall the blinds.
We noticed that the metal tape would sometimes scrape against the glass. If this is the case for you, remove the blind from the window and fold tape along the backside edge of the metal tape/blind, then reinstall the blind.
Since the magnet is placed in front, it doesn’t affect closing the blind, but it will protect the glass.
