Red Blood Cell Amigurumi

Amigurumi Projects, For Science!

Amazing what you can get done while procrastinating, isn’t it?  That’s my justification, anyway.  Here’s a very simple pattern to crochet an erythrocyte (red blood cell), but if you leave out the middle piece the same pattern could be used for any toroid shape.  Like a donut, or .  Just sayin’.

Outer ring:

  1. ch 12
  2. sc x 3 (1st in ‘tail’ of chain to close the circle), hdc x 5, sc x 4 (12)
  3. sc x 3, then continue around hdc x 5, sc x 7 in each round until ring can be closed

This may take more than or fewer than 32 rounds depending on your yarn and hook size (worsted weight yarn and 3.75 mm hook used here, for a finished size of 8cm/3″). Stuff and sew closed, affixing safety eyes (15mm here) if goofy-looking RBC is desired.

Center disc:

  1. 6 sc in magic ring (6)
  2. inc x 6 (12)
  3. inc x 6 in 1st 6 sc (more if needed depending on size of donut hole)

Sew in place. LOL a bit. Then check out this video of Party Rock Anthem and contemplate using the pattern to make an ‘O’.

    1. You don’t increase… the 1st ‘sc x 3’ is just to reset the point where you start the hdcs (so each round is 12 around: 5 hdc and 7 sc)

      Thanks for the question and hope that helps!
