I am not familiar with the shops in San Clemente, but if you can get down to San Diego, here are some to see:
http://www.quiltersparadiseesc.com in Escondido
http://www.rosiescalicocupboard.com in San Diego
http://www.cozyquilt.com in Rancho San Diego
Hopefully the quilters that live north of me can help you with those closer to San Clemente
