How do you get pen ink out of a wool hat with out ruining it?

The stain may be more or less permanent.

Try this:

**Soak the hat in lukewarm water with a mild soap added for three to five minutes.

**Push the soapy water through the stain several times, taking care not to agitate the wool.

**Continue to soak and work the hat until no more ink comes out.

**Rinse the hat twice by filling the bowl with fresh water then pushing the water through the hat. Drain the bowl each time and continue to push fresh water out of the hat.

**Roll the hat in a towel to remove excess water. Do not wring.

**Air dry flat after coaxing the hat back into the shape you want.
