William Townsend from Element Church in Wentzville, MO brings us these lettered towers.
They build these multi-purpose light boxes. They made them 6×3′…one foot deep. They used Coroplast to cover the boxes and frames made from 1×1″ furring strips. They held the boxes together with 3-inch screws and held the Coroplast on with 1-inch screws and lock tight. On the inside, they taped black letters cut from Coroplast so they could only be seen when the box was lit up.
