Lay the canopy vertically in front of you on a flat work surface such as a clean floor. Measure the width and length of the canopy and write down those measurements.
Screw two large bicycle hooks into the top of the slanted wall, spacing them apart the measurement of the width of the canopy that you wrote down in Step 1. Bicycle hooks are ideal because their large size will allow the canopy to billow outward from the wall elegantly.
Measure vertically down from the bicycle hooks to a spot on the wall that is 1 foot shorter than the length of the canopy. Mark this spot with a piece of chalk in two places: beneath the upper right and left hooks.
Screw a bike hook into each chalk mark. Attach the canopy to each hook either by sliding each hook through the corresponding slit or hole of the canopy, found in each corner, or by knotting the attached ties the canopy has coming out from each corner around each hook. The canopy will gracefully billow out from the wall.
