This tutorial is the follow up of my reversible fabric and vinyl bag on how to make an adjustable strap.
This adjustable strap consists of two straps –one longer and one shorter– joined together by a buckle with lobster claws at both ends.
The procedure for making the straps and loop are the same. To avoid showing an unfinished edge we are going to make the edges of the straps meet at the center. Then we are going to glue the vinyl and fabric together and sew the sides. Once both straps and loop are done we are going to attach the hardware.
- Two strips of vinyl 19″ X 1.5″(48cm X 4cm) and one 36″ X 1.5″(91cmX 2cm).
- One strip of fabric 32 “ X 1.5″(81.3cm X 4cm)
- One strip of fabric 19″X 1.5″(48cm X 4cm)
- One rectangle of vinyl 3″ X 1.5″ (8cm X 4cm)
- One buckle 1″ (2.5cm) wide
- Two lobster claws 1″ (2.5cm) wide
How To Make An Adjustable Strap
We are going to be making two straps and one loop. The assembly instructions are the same for the three pieces.
There is a short strap and a longer one, these straps are both going to have a fabric facing.
This adjustable strap can be expanded between 46″ to 40.5″ (117cm to 103cm) in length.
Making The Longer Strap
The longer strap will have a lobster claw on one end and holes on the other end.
Take the longer strip of vinyl 36″ X 1.5″(91cm X 4cm).
Mark the middle of the strip by diving the strip in two and mark each half again in the middle. You will end with three lines on the strip that are exactly 3/8″ apart.

Bring the top and the bottom to the center line. Press and let it dry, use clips to make sure the strap is going to dry flat.
Take a strip of fabric that is 32″ X 1.5″(81.3cm X 4cm). Divide the strip lengthwise in four equal parts of 3/8″ (1cm) as shown below and using the same technique as above. Bring the bottom quarter towards the center.
Now we are going to glue the fabric strap to the vinyl strap.
Apply glue to half the space that does not have glue, let it dry for about 3 minutes and fold the strap over the ring of the lobster claw. Align the edge of the vinyl with the beginning of the fabric strap.
The shorter strap will have the buckle and a loop on one end and a lobster claw on the other end.
You will need the strip that is 19″ X 1.5″ (48cm X 4cm) in vinyl and another in fabric.
Glue the strip of vinyl and the fabric as above and then glue them together.
Remember to leave 2″ on either end then glue and fold the ends. Use clips to keep the ends from coming apart. Leave it to dry for 10 to 20 minutes.
Take the rectangle 3″ (8cm) X 1.5″ (2cm).
Mark the middle of the rectangle using a ruler. Apply glue on the wrong side.
Now we are going to make this little strap into a loop then glue it to the strap.
Place the strap on the table fabric facing up. Slide the small strap under edges meeting on the fabric side placing it 2.5″ (6.4cm) from the end. Apply glue under the small strap that now becomes a loop.
Make sure the lobster claw faces the opposite way as the other lobster claw.
What to do if you do not have enough vinyl to make a long enough adjustable strap?
This is exactly what is happening to me since I only bought a meter of vinyl and so far I have made two tote bags, one clutch, and this adjustable strap so I don't have enough to make it long enough.
So, I'm going to use a slider to attach two straps together to make it in the length I need.
Make an extra strap following the same procedure as above except that you are going to use a square ring or a slider to attach two straps to make a longer one.
