As a DIY expert with years of experience transforming everyday fabrics into weather-resistant outdoor furnishings, I recommend durable beach towels for slipcovers. Spilled ice and piña colada withstand easy washing, while the fabric stays cool, absorbent, and vibrantly colorful.
For square cushions, align patterns to run up the sides. Drape the towel over the cushion, trim excess fabric leaving a 1-inch seam allowance. Use a solid-color towel (inexpensive option) for the back.
Unfold the fabric and mark corner folds with pins or a fabric marker.
Turn the towel over and trim excess fabric from the corners.
Sew the corners to form a box shape at the bottom. Cut the bottom piece to size plus seam allowance. Pin it to the sides and sew three of the four sides for the box seat cushion.
Sew Velcro to the remaining opening. This allows easy removal and washing.
Extra-large beach towels work perfectly for back pillows. Sew into a large tube with the seam at the back and design centered on front. Close one end and add Velcro to the other. Stuff with two extra-large, extra-firm pillows.
For seat cushions, create Velcro tabs and cover them with matching fabric.
Machine wash regularly and apply water-repellent spray to keep cushions like new.
