About this pattern

The Diamond Gem is a free foundation paper piecing (FPP) pattern from NiftyFifty: a 12-inch square block of 13 pieces sewn in 2 sections, using 5 fabrics, at a 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.

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 6″ and up.

Finished block	Smallest piece
6″ × 6″	about 0.7 sq in
8″ × 8″	about 1.2 sq in
10″ × 10″	about 2.0 sq in
12″ × 12″ (as drafted)	about 2.8 sq in
16″ × 16″	about 5.0 sq in

A sewing tip for this block

Alternate a light and a dark on the crown facets, then use your two deepest fabrics on the pavilion for sparkle.

What to make with it

The gem makes a quick, sparkly pillow or a mug rug, and it's a good block for an anniversary or birthstone gift.

Try it in other colors

Color it to match a birthstone, like a ruby red, emerald green or sapphire blue. Every fabric can be swapped in the FPP tool before you print.
