Christmas in July

I recently participated in a fun Christmas in July swap through The Switchboards. My secret pal was Tricia of sevensixdesigns . She sent me some really cool cards. I like these circle ones the best--she must've known I like circles! These cards look like they are handprinted, perhaps with a print Gocco? Maybe Tricia will see this post and enlighten us as to how she made these cool designs.
