A fun thing about the Twitter "Twemoji" is that they're freely licensed - so here are five of them in embroidery form.
They all fit within an 18mm square, perfectly sized to go on my small square or octagonal snap tabs - and as a bonus, these five are pre-populated in the 4x4-friendly 5-up version. Stitch them on the square ones right from these files, or merge them with the octagons for quarter keepers - the layout is the same.
They're also a great size for the Jumping Spider, if you want a few more variations for its "spot."
The files come in all the formats Ink/Stitch can produce, along with the SVG source file that you can edit or resize in Inkscape+Ink/Stitch.
