We LOVE these half umbrellas for creating inexpensive awnings over our guest house doors. After pricing awnings and not finding anything that fit our budget and style, we thought these would be a temporary fix to add charm and shade the entryways. We are very pleased with the results. Because the umbrellas had to be offset from the entrance, and they were slightly wider than our space, we cut  the back spines a couple inches to fit and tucked the extra fabric under. The results are better than we hoped for. The umbrellas are held in place by two hooks and black zip ties, which disappear against the pole and allow the umbrella to open and close, and be listed out if needed.
