Since I released my Monstera Leaf Crochet Mug Rug Pattern a few weeks ago, I have been really enjoying making crochet mug rugs. I particularly enjoy making crochet mug rugs that have fun images on them. Since it is summer, I wanted to come up with a fun and summery crochet pattern and at our house, we really like crabs so I decided to create a crochet crab mug rug free pattern. We named it the Happy Crab Mug Rug. This free mug rug pattern is accessible for beginners and even better: there are a few ends to weave in! Most of the ends are tied off on the sides to create the tassels and the only ends to weave in are the black yarn ends. If you want to have the odd black yarn strand in your tassels, you could just carry the yarn and have no ends to weave in, should you prefer that. But either way, this crochet crab mug rug free pattern is a lot of fun to make.

Before we get into the Happy Crab Mug Rug pattern, let’s talk about the technique that I used for this and why it’s so much fun. Tapestry Crochet was used to create this crochet crab mug rug free pattern and you will be working your project with the right side always facing you. Unused yarn is carried as you work each row and both colours are finished off at the end of each row, reattaching your yarn in the first stitch for every new row. To create the tassels, you’ll leave a tail of a few inches on both sides of the project and trim them up at the end. When we introduce the third colour into our project, the black yarn, it will be the only yarn ends you’ll have to weave in. The red and white yarn are worked from end to end and used to create the tassels. If you don’t want the tassels, you can weave in your ends if you choose but I think it adds to the rug feel of my little crochet mug rug.

**I have made the Happy Crab Mug Rug pattern free on my blog so as to make it as accessible for as many people as possible. Please do not copy the pattern or remove it from my blog in any way. If you would like to have an ad-free or offline copy of the pattern, they are available for a small fee in my Ravelry and Etsy shops which helps support my blog so that I can continue to provide free crochet patterns like this for everyone.**

Gauge isn’t critical for this project, but keep in mind that not matching gauge will affect the size of your crochet mug rug and how much yarn that you will use. Yarn yardage given for this project is approximate and based on the gauge given.

For this project, I used my favourite multi-purpose cotton yarn: WeCrochet Dishie. You’ll need the colours Black, Fiesta Red and Swan (White) if you want to match my crochet crab mug rug exactly but crabs come in a variety of different colours so have fun mixing it up. I plan on making a blue crab for my next Happy Crab Mug Rug.

Purchase an inexpensive ad-free PDF version of this pattern which includes the written version and the colourwork chart HERE on Ravelry and HERE on Etsy.

This project uses a colourwork chart to illustrate the crab image. This chart is to be read from right to left for right-handed crocheters and left to right for my left-handed friends. If you’d prefer to have the colour changes written out for you, the ad-free PDF version of the pattern includes both the colour chart and the full written version of the pattern. Ad-free PDF versions of this crochet crab mug rug free pattern are available in both my Ravelry and Etsy shops.

  • BLO = Back Loop Only
  • CH = Chain
  • ST = Stitch
  • SL ST = Slip Stitch
  • SC = Single Crochet
  • FO = Finish Off

Finished size:

  • 5.25” tall by 5.75” wide not including fringe


  • 22 sts x 17 rows = 4 inches


  • Gauge is not vital to the pattern but it may affect the size of your project and the amount of yarn required
  • Carry unused colours and crochet over them as you work.
  • This entire project is worked in rows worked in the BLO (back loops only). When reattaching your yarn at the start of a Row, attach your SLST under both loops of the first ST.
  • When starting each row, leave a tail a few inches long of both main colours (red and white) hanging on the edge of your work so you will have fringe on both sides.
  • Each row ends but fastening off both colours, leaving a tail of a few inches to create your fringe (you’ll trim it up at the end)
  • Attach black yarn as needed in the pattern but do not carry to the yarn to the end of the row. Cut the yarn when finished in each row and weave in the ends. Alternatively, the black yarn can be attached and carried as outlined above and you won’t need to weave in any ends.
  • Start Rows 2-22 by reattaching the main color yarn to the first ST of the previous Row and carrying the yarn inside your stitches.
