My dear friend is getting married this July. Her theme has aspects of the early 1960's as well as wedding colors of yellow & white. So we have coordinated on a few projects long distance
I purchased my punch at JoAnn Fabric while they were running a sale on punches (which is often).
To make the garland: Unwaxed dental floss (I couldn't tell you when I started using it for certain projects, but its sturdy enough for me without being bulky), hot glue gun, & extra glue sticks.
To assemble the garland, put a dot of hot glue on the back of a flower, Lay the floss over the glue and sandwich another flower on top of the glue. Rinse. Repeat.
