## Extra Steps for PLA

If you don't have flexible filament, you can use regular PLA instead, with a few extra steps. To curve the letterforms, dip in just-off-the-boil water for a few seconds, then lay the part on your hat.

Keep in mind that parts heat unevenly, and don't expect to get more than a general curve&nbsp;out of this step. This is not a precise process. =D

You may also have to drill out the sew holes with a small bit and rotary tool to enable the needles to pass through.

## Affix to Hat

While not strictly necessary, pins are very handy for determining the placement of your parts on your hat.

&nbsp;

Thread two needles onto your thread, one on each end (or one at the center with the thread doubled, as shown, with the other needle threaded onto both tails).

![3d_printing_custom-hat-text-03.jpg](https://cdn-learn.adafruit.com/assets/assets/000/023/670/medium640/3d_printing_custom-hat-text-03.jpg?1425483936)

Pierce through the sew tabs with both needles, bringing the ends to the inside and leaving a clean loop securing the part to the hat on the outside.

For a flush fit, it helps to keep the pins in place until the knot is tied at the inside.

Tie off at each tab and snip the thread tails short.

Don't like your placement or design? No problem! Just snip the threads with scissors or a seam ripper and reposition or replace your design.
