This is a plushie design, made "in the hoop" on an embroidery machine. It produces little plush sharks that you can keep, gift, or sell.The smaller two sizes can be made in a 5x7 (130x180mm) hoop, up to the largest in an 6x10 (150x250) or 8x8 (200mm) hoop.

The only hand-sewing is closing the turning opening.

The files come in all the formats Ink/Stitch can produce, along with the SVG source file that you can edit in Inkscape+Ink/Stitch.

You can make plushies to sell, and I highly encourage it.
