A sandy swimsuits is usually not a good thing, but in this case it is!
Show your style at the beach with a sand pattern swimsuit, a swimsuit with a stenciled sticky application on the fabric that reveals a custom pattern after lying in the sand. The sand can then be washed away simply by swimming in water. When you're ready to show off your pattern again just lie in the sand. The best part is that the pattern can be anything you want!
The secret is a thin film of silicone caulking applied through a stencil. The silicone is elastic and can flex with the movement of a swimsuit, staying durable and firmly in place. This project explores the concept of applying flexible silicone to a swimsuit. The results were a success, but took some trial and error.
Step 1: Supplies
- 100% clear silicone caulking
- card stock
- hobby knife
- Lycra swimsuit (or similar stretchy swimsuit fabric)
- binder clips
It's a good idea to wear protective gloves when applying the caulking, and to work in a well ventilated area.
Step 2: Make stencil
sketch your pattern onto cardstock. You want to use thin cardstock so when you apply the caulking through the stencil you're left with a thin layer and not a goopy mess.
I recommend trying out your template on scrap fabric first, and to print out multiple copies of your stencil, as they are bound to get soiled while applying the caulking.
Here are some templates I made for my swimsuits, you can download and use them if you like.
Step 3: Cardboard form in swimsuit
Before applying the stencil the swimsuit needs to be secured to a flat surface in order to make a clean stencil transfer. A section of cardboard was cut and slipped inside the swimsuit, and gently stretched flat and smooth.
The swimsuit was then held to the cardboard with binder clips.
Step 4: Clip stencil to swimsuit form
Next, clip the stencil over the swimsuit, using more binder cips to hold it in place.
