First, cut up the bed linen to the right length. It should be long enough to cover the tea towels. Sew a loop at the top short end for the fabric to be threaded through the tension rod.
I cut both sections of the cheap white tension curtain rod into the correct length. You need to thread the fabric along the rod so do make sure they can be assembled from both sides.
To hold up the rod, I drilled holes into the side of the TORNVIKEN shelf. The tension rods had two different diameters: 10 & 11 mm. So I drilled two different diameters to match, 11 & 12mm to minimise the gap.
Be careful when drilling in MDF as it’s happy to split. Use tape over the area to be drilled to reduce splitting. Countersink and paint the exposed area with matching white color when done.
Assemble the TORNVIKEN wall shelf. Add in the extra FINTORP hooks to the metal rod, if necessary. Slot in the tension rod with fabric to the holes on the side. Finish with finials, if you wish.
Hang up your tea towels behind the curtain. All neat and tidy.
