You Called Three Companies.
All Three Said No.
“We only make rectangular shades.” Two companies didn't even let you finish describing the window.
Pairing opposite-sloped windows requires mirror-matched flat top trapezoid shades from the same fabric lot.
You searched online and found stock photos, vague “call for quote” pages, and zero real pricing.
Your window isn't the problem. The industry is.
We cut matching left and right flat top trapezoid pairs from a single fabric roll — guaranteed color match, opposite angles.
The left flat top trapezoid is the mirror image of the right — the top is flat and level, but the bottom angles with the shorter side on the left. This appears on the opposite side of sloped sills, stepped foundations, and paired architectural windows.
Like its right-side counterpart, the flat top means this shade mounts on a standard roller tube and operates normally — you can raise and lower it. The angled bottom edge follows your window slope precisely.
If you're covering a pair of windows with opposing slopes, order one left and one right flat top trapezoid from the same fabric. We'll cut both from the same roll for exact color matching.

Common Questions
Flat Top Trapezoid – Left Shade FAQs
A regular trapezoid has the angle at the top (the top edge slopes). A flat top trapezoid has the angle at the bottom (the top edge is flat/level). The flat top version can roll up because the roller tube sits on the level top edge. Regular trapezoids are stationary.
Yes — this is a common order for windows on either side of a sloped sill. Add both to your cart and select the same fabric. We'll cut from a single roll for exact color consistency.
Flat top trapezoids use the same specialty pricing grid. Since they require more fabric than a comparable regular trapezoid (the angled bottom means more material on the longer side), the price may be slightly higher for the same overall dimensions.
