A, material preparation:

Cloth: choose durable and easy-to-clean cloth, and choose colors and patterns according to your own preferences.

Filler: you can choose the filler suitable for the cushion, such as sponge, cotton, foaming material, etc.

Sewing tools: sewing machines, threads, needles and other basic sewing tools.

Measuring tools: ruler, scissors, etc.

Second, the production steps:

1. Measurement and design

Measurement of length and width: Measure the length and width of the bench with a ruler to determine the required seat cushion size.

Increase seam edge: according to the actual size, increase the width of seam edge. Usually leave a hem of at least 1.5 to 2 inches (3.8 to 5 cm).

Cut cloth

Cutting cushion cloth: according to the measured size, mark the cloth block with scissors and cut it according to the measured size.

Cut two pieces of cloth: cut two pieces of cloth the same size as the top and bottom of the cushion.

Sewing seat cushion

Sewing: Align the inner sides of two pieces of cloth, then sew the edge cloth with sewing machine or manual needle and thread, leaving a small opening for filling the seat cushion.

Turn-over filling: Turn the sewn cushion fabric over to the front, fill the interior of the cushion, and add a proper amount of filler as needed to ensure the fullness of the cushion.

Sealing and stitching

Hand sewing: sew the seal of the seat cushion by hand with needle and thread to ensure that the filler will not overflow from the seal.

Adjust neatly: tidy up the edge of the seat cushion to ensure that the filler is evenly distributed and there is no foreign body.

5. Testing and placing

Testing and installation: put the prepared seat cushion on the workbench to ensure the proper size.

Fixing the seat cushion: according to the need, a rubber belt, zipper or bandage can be sewn or fixed at the bottom of the seat cushion to fix the seat cushion on the bench.

Third, matters needing attention:

When sewing, ensure that the sewing thread is strong, and avoid the overflow of filler caused by excessive gap.

The choice of filler depends on personal preference and comfort, and the hardness of the cushion can be adjusted as needed.

The above are the general steps to make a long bench mat. When making, pay attention to the accurate size and firm sewing to ensure the neat appearance of the cushion. I hope these steps can help you make a satisfactory long mat.
