A1: Material can look quite different once daylight passes through it. Test the sample against the glass rather than judging it only on a table.

A2: View them in morning, peak sun, overcast light, and evening interior light if possible. The same material can look different at each time.

A3: Backlight it at the window and view it from both sides. A small sample cannot reproduce every edge condition, but it reveals material opacity and silhouette risk.

A4: Compare weave openness, surface texture, coating, stiffness, pattern scale, backlit appearance, and how the material feels beside furniture and flooring.

A5: It can demonstrate the material, but the finished treatment also depends on layers, slat or vane position, mount, overlap, and edge gaps.

A6: Label each with product, color, opacity, and room. Photograph them at the window and record which problem each option solves.

A7: Yes when the same color may be used across different window directions or room finishes. North, south, east, and west light can change the result.

A8: Order after confirming color, texture, light effect, privacy, care, product compatibility, measurements, mount, control, and any charging or power requirement.
