*Each kit contains the components required for ONE corner. Triangle shades will require 3 kits, square shades will require 4 kits.

Today is Earth Day 🌍

When you are planning your next project, consider beyond just the upfront cost. Think LIFECYLE.

Investing in materials that last longer might cost you more at the start, but over time it means less waste, fewer replacements, and a more sustainable future. ♻️

Choose durability. Choose responsibility. Choose better for the planet. 🌱
