Monterey Kelp is my first exploration of the improv piecing technique. After piecing the quilt top, the alternating pieced wedges and navy wedges resembled light filtering down through a thick kelp forest to me. To accentuate this, I chose to quilt the improv wedges with straight lines so they would remain smooth like blades of bull kelp, while I quilted a curved motif in the navy wedges resembling bubbles rising through the deep water.
