This is designed as an in-the-hoop pattern for an embroidery machine but you can also sew it with a conventional machine and use safety eyes.
It’s pretty simple: hoop up and embroider the top of the body, then put a second piece of minky on, right-sides-together, before “embroidering” the outer seam. Unhoop it, cut it out and turn it, then hoop up and “embroider” the seam of the legs, cut them out and turn them. Stuff the body, wire the legs with pipe cleaners if you want, then hand-sew the two pieces together and you’re done.
If you’re sewing with a conventional machine, or you’d like to play around with Inkstitch to see how embroidery pattern design works, you’ll want the SVG version. To make a pattern for conventional sewing, hide one layer, print, unhide, hide the other layer, print. Bonus: you’re not limited to a 4×4” spider. Remember that the lines are sewing lines, not cutting lines.
If you’re embroidering, pick the file that works best for your machine. Caveat: I’ve only used the Brother PES file, but there’s nothing too boundary-pushing in this design so I expect the other versions to work fine. One exception might be in sizing – it runs up against the boundaries of my machine’s “4×4” hoop so let me know if I need to size it down to meet the exact specs of other brands.
