About this pattern

The Spool of Thread is a free foundation paper piecing (FPP) pattern from NiftyFifty: a 12-inch square block of 21 pieces sewn in 3 sections, using 7 fabrics, at a confident beginner 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.

Piece map

Letters are sections, numbers are sewing order. Dashed lines outline each section's foundation.

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 12″ and up.

Finished block	Smallest piece
6″ × 6″	about 0.1 sq in
8″ × 8″	about 0.2 sq in
10″ × 10″	about 0.3 sq in
12″ × 12″ (as drafted)	about 0.5 sq in
16″ × 16″	about 0.9 sq in

A sewing tip for this block

The loose end is a narrow strip. Cut its fabric a generous half inch wider than the paper and trim after sewing, so the line stays crisp.

What to make with it

Put one on a pincushion top or a sewing machine cover, or make a row of spools in different thread colors for a sewing room mini quilt.

Try it in other colors

Wind the spool in the thread color you reach for most, or use three prints of one color for a variegated look. Every fabric can be swapped in the FPP tool before you print.
