Free Crochet Pattern – Mr. Sa – the Superbug, MRSA

Here at Drunken Aunt Wendy Designs, I’ve been continuing my crochet microbes series. Below you will find a pattern for Mr. Sa. He’s MRSA under the microscope. He’s got a cape because he’s a superbug. I think I’m going to have to crochet an antibiotic in order to fight off all these diseases.

But before we get to your free pattern, lets check in on everything else I have been up to.

I finished my gingham plaid scarf. I went a little crazy on the color scheme settling on Lime Green and Blush.

This one I made with worsted weight acrylic yarn. I don’t think I will use the same kind of yarn in the warp as it was a touch sticky in the heddle. The next scarf will be purple silk made out of lace weight yarn. It should have amazing drape.

Last week I also found a bonus sweater. What is a bonus sweater? Well it is a completely knitted wool cable sweater that just needed the arms sewn on. Exactly how many projects do I have going that I forgot I knitted a sweater. I mean seriously.

It is made out of Wool of the Andes Yarn in Sapphire Heather from Knit Picks. I’m a big fan of this site. The yarn is very reasonable and makes sweater knitting significantly cheaper. The pattern is called the Central Park Hoodie. It is one of my favorite patterns. I have knitted it a couple of times. The end project is super cozy. I did go up a size on the arms as my biceps are huge. (knitting apparently beefs them up, lol).

Now what you have all been waiting for. Here’s the crochet pattern for Mr. Sa, the MRSA superbug.

If you haven’t visited me before, the free patterns are not tested. Tested versions with lots of photos are available in my Etsy or Ravelry shops. If you make Mr. Sa, make sure to use #drunkenauntwendy so I can find it on social media. Don’t forget the other crocheted microbes, Anthrax and Mr. Sniffles.

Worsted Weight Yarn
I love this yarn in Old Leaf
I love this yarn in Black
12 mm Safety eyes
Size E crochet hook
Large Eye Needle

Gauge is not important for this project unless you have purchased a kit. Using the right size hook is important to ensure you have enough yarn.

SC – Single Crochet
HDC – Half Double Crochet
DC- Double Crochet
CH- Chain
FO – Fasten Off
SL ST – Slip Stitch
INC – Make two Single Crochet in Same Stitch
DEC – Single Crochet two stitches together
BLO – Back Loops Only

Note: Entire project is worked in the round. Use a stitch marker or a scrap piece of yarn to mark the beginning of each row. Then you don’t have to count every row. Do not join unless instructed to.

Parentheses indicate a repeat. Repeat the stitches in the parentheses for the number of times indicated.

The bracketed number [] is the number of stitches at the end of each row.

I spread my increases out so there isn’t a seam on the finished piece. If you do not like this method, you can do regular increases.
