L'Écheveau Solidaire is a fundraising initiative for medical research operated by the French nonprofit association MASFD, focused on finding treatments for those touched by two specific diseases: McCune-Albright Syndrome, and fibrous dysplasia of the bones (referred to as FD/MA when found together).

100% of the profits made from sales of L'Écheveau Solidaire products are donated to MASFD. Thanks to your generosity, and the generosity of those who have donated illustrations, patterns, and other assets over the years, we have been able to donate more than €145,000 to grants and research projects since 2018.

If you would like to learn more about making donations directly to MASFD, please see our Donations page.
