FPP Lobster Quilt Block
This claw-some crustacean critter is fully armored in a rugged red shell (after a quick spa session in hot water), with two built-in multi-tools: one claw for crushing and one for pinching—because versatility is im-prawn-tant. Use this block for your coastal adventures and bucket list quilt.

Under the Sea Appliqué Pillow
The Under the Sea Appliqué Pillow Pattern makes a splash with seven sea-worthy appliqué designs to choose from and personalize your project. Create a pillow that suits your style—go bold with layered motifs or keep it simple with a single ocean-inspired element front and center.
