What are some DIY wedding decorations for a wedding in a garden?

A garden already has beauty, so your DIY should enhance it without fighting it. For the ceremony, make a simple arch from two wooden posts or a freestanding frame, and drape it with muslin or a garland of ivy and flowers. If you have a tree or a hedge, use that as a natural backdrop. Line the aisle with potted plants, which you can later give as favours, or with paper lanterns on stakes. For seating, use hay bales covered with throws, or wooden benches you can borrow or hire. For the reception tables, use wooden crates or logs as stands for flower arrangements in jars. Wildflowers in a mix of colours look natural and are easy to arrange. You can also make a table runner from a strip of hessian or linen, and scatter petals or leaves along it. For lighting, string fairy lights between trees or along a fence, and use candles in lanterns for the evening. A simple sign on a wooden board can point guests to the ceremony or the bar. If the weather might turn, have a backup plan: an indoor space or a marquee, and keep decorations portable so you can move them quickly.
