About this pattern

The Jellyfish is a free foundation paper piecing (FPP) pattern from NiftyFifty: a 14-inch square block of 84 pieces sewn in 24 sections, using 4 fabrics, at a advanced skill level. It opens in NiftyFifty's free browser-based FPP tool, which prints mirrored foundations with 1/4-inch seam allowance at 4 to 18 inches. Every seam is a straight line, so the whole block is sewn with the flip-and-sew method.

Choosing a block size

Smaller blocks mean smaller pieces. Under about half a square inch, pieces get fiddly, so this one is most comfortable at 16″ and up.

A sewing tip for this block

The tentacles are zigzags of short strips, so match each turn carefully and press toward the navy. A shimmery or batik print on the bell looks lovely against a dark background.

What to make with it

Great for an ocean themed baby quilt, a kid's bedroom pillow, or alongside the starfish and shell in a sea life sampler.

Try it in other colors

Try glowing aqua and sky blue on black, or orange and coral like a sea nettle. Every fabric can be swapped in the FPP tool before you print.
