Step 2: Cut out the pattern pieces

Place your pattern on top of your latex sheeting, and cut out the various pattern pieces using a rotary cutter on top of a cutting mat.

** When you cut out the trim pieces, add an extra 1/2 inch to the ends - if it's too long you can always cut away the excess, but if it's too short, you'll have to cut a new piece. **

Step 3: Glue front trim to front section

  1. Place the front section on your working surface and then layout your front trim pieces on top of it to ensure that everything comes together properly.
  2. Mark the location of the trim pieces on the front section.
  3. Brush on glue to the front section where the trim will go. Make sure that the glue is slightly wider than the trim.
  4. Starting at one end, adhere the trim to the glue. Working slowly down, and making micro-adjustments as you go.
    • Try not to stretch the trim as you adhere it to the rear section.
  5. Press the trim to the front section using your seam roller.
    • Use as much pressure as you can.
    • Roll at a 45 degree angle to the trim.

Step 6: Glue the front to the rear

Brush on glue to both the rear and front where the seam will come together. Use a 1/4 inch width seam.

If the seams don't match up perfectly, carefully trim the overage with your rotary cutter. If the seams are off by more than 1/4 inch, gently pull them apart and start again.
