How it's made
How eyelet curtains work
Tap a number to see what each part does, and what you'll be choosing at your appointment.
1. Eyelets
Metal rings through the heading sit straight on the pole, with no hooks or gliders in between — very little to catch or snag.
Your advisor brings samples of every option to your window, so you can see and feel them before you choose.
Why this range
What Penumbra does well
01
Built as blackout curtains
Cut and finished as blackout curtains for your exact window, rather than trimmed down from a stock size. The mechanism is sized to the drop, so it hangs straight and stays that way.
02
2 colourways to compare
Colour behaves differently in north light, in the evening and against your walls. Pick the ones you like here and your advisor brings those exact swatches to the visit.
03
Chosen for real rooms
Customers most often put this range in bay window curtains, bedroom curtains, door curtains — which is a better guide than any spec sheet.
Style notes
What Penumbra is like, and where it works
Penumbra is a geometric print in navy and white, shown here as a roman blind and as pinch pleat curtains. The interlocking circle pattern reads as a fairly dense, tailored design that works equally well as a single window dressing or paired with a plain venetian blind.
A dark navy and white geometric print of interlocking circles, giving a lattice-like repeat pattern with a woven, textured finish.

- pale or mid-toned wood flooring

- muted blue or teal wall colours
Ideas for your home
Made-to-measure roman blind for a home office
Suits a room with dark wood furniture and a mix of jewel and neutral tones, where the blind becomes the main pattern against plain walls.
The dense geometric print gives a working space some visual interest without needing extra artwork.
Made-to-measure pinch pleat curtains for a dining room
Works well in a room with pale or mid-toned wood flooring and coloured walls, framing tall windows alongside a plain venetian blind.
The tailored pleat heading and bold print give height to full-length windows in a room used for entertaining.
Made-to-measure curtains for a bay window
Suits a bay window with a mix of painted and wood-toned furniture, where the pattern draws the eye along the run of the bay.
The repeat pattern reads clearly across multiple curtain widths, useful for wide or bay windows.
- Available as curtains (eyelet, pencil pleat or pinch pleat headings) or as a roman blind, so the same pattern can be used across different window types in one room.
- Comes in two colourways, Mimosa and Denim, both featuring the interlocking geometric print.
- Listed as blackout and thermal, so it is worth checking these properties with an advisor when discussing bedroom or living room use.
