I don't see anything! When I searched I found Lax... but relax and galaxy. Who are your fav designers? I'd tag them and ask if they might be able to create something fun!
But as a general idea... maybe just sports related? Or a big cut out word from Liz for one sport might work for Lax.
This kit has the word art Lacrosse Studio liv has the Lacrosse word art too in her The college Experience Kit. Kristin Aagard has a sporty kit selection. None are specifically lacrosse, but one of them might work with the other sporty pieces.
