Here’s what you need to know!

Interlocking Crochet

  • Also known as double filet crochet, triple filet crochet, locking crochet and intermesh crochet.
  • Interlocking Crochet uses a technique that combines two, or more filet mesh stitch patterns together to create intricate geometric and mosaic designs.
  • This means, the finished fabric is double thick because you are essentially placing 1 piece of crocheted fabric on top of a second piece of crocheted fabric and working around and through the opposite color of stitches.
  • You are never actually working into the fabric you are crocheting with the other color of yarn. When you are working with Color A Yarn, you will never crochet into Color B Yarn.
  • You will work around the stitches and spaces you crocheted in Color B yarn and then back into the Color A Yarn side of your fabric.  This creates 2 pieces of fabric that are stuck together by working around the chain spaces and stitches of the opposite color. When you look at the back, there is a different design than the design on the front.

You can create great mosaic designs using this technique but it is not actually the same as Mosaic Crochet.

You can see a great visual example of how use the interlocking crochet technique in this post from Tanis Galik:

Interlocking Crochet Techniques

Mosaic Crochet

  • Mosaic Crochet is similar to Mosaic Knitting. 
  • You follow charts which are worked back and forth in rows, using a single color of yarn for every row you work.
  • The finished fabric is thinner because you are only working with one fabric layer.

For the purposes of this explanation I am using white and black yarn.

Example Mosaic Crochet Chart

To begin you will work your foundation row in single crochet. You would choose the opposite color to the first square on the bottom right of the chart. So if your chart has a black square in the bottom right corner, you would begin with your white yarn and work 1 row of stitches (the same number as the chart across = 10) in foundation single crochet (FSC).

  • Row 1: Using white yarn work 10 FSC.

Then you would begin working the chart back and forth in rows.

  • Each row on the chart represents 2 rows.
  • So, you begin bottom right and work across the chart from right to left (from the 1 to the 2), then turn your work, ch 1 and work back across the same row of the chart, from left to right (from 2 to 1).
  • The return row will be the same as what you just crocheted.
  • At the end of Row 2 you can either finish off your yarn or carry it up the side edge of the project if you are adding an edging later on.

When you are working the rows in black yarn:

  • For every black square on the chart, you will single crochet and for every white square you will chain.
  • When you chain, you chain the number of squares in white + 1 extra chain.

When you are working the rows in white yarn:

  • For every white square that is located above a black square, you will work a single crochet.
  • When you see a white square over a white square, you will work in front of the chain stitches and crochet a dropped double crochet stitch into the sc 2 rows below.

When you look on the back, you will see horizontal rows of each color in Mosaic Crochet.

There is a fantastic tutorial available at ClearlyHelena to explain how Mosaic Crochet is done when following a Mosaic Knitting Chart.

Dropped Double Crochet Method

An alternate method for Mosaic Crochet is loosely based on mosaic knitting. It is the Dropped Double Crochet Method from Shady Lane Crochet. She has a video tutorial and lots of beautiful patterns designed using this method and it is super simple to master.

    1. Hi Tara, I’m not going to change the post to remove the references because I have indicated that it is being referred to as the same as Interlocking Crochet. Since Designers and Readers alike are actually using the terms interchangeably, I think it is still important to reference both in the article – I am adding your comment to the post because I believe it is valid issue and it may help people clear up the differences. To be honest I didn’t realize there was a difference because most of the information I was referencing online indicated they were one and the same type of technique. From your explanation, it sounds like Mosaic Crochet is very similar to Overlay Crochet…and many who are calling their patterns Mosaic Crochet are actually making Overlay Crochet Patterns (like the Mandalas I have crocheted in the past which has a flat back and single colors for every round on the back. Feel free to email me or use the contact form to send me some references online that specify the differences and I will add some more information to my post for my readers 🙂 All the best, Rhondda

    2. I didn’t know how else to contact you, but Mosaic Crochet and Interlocking Crochet are NOT THE SAME. Mosaic Crochet works like Mosaic Knitting, working one row (or round) in each color and using a taller stitch (sl st in knitting) to create the vertical lines. When you look on the back, you will see horizontal rows of each color in Mosaic Crochet.

      Interlocking crochet (AKA Double Filet and Locking Crochet) is a different animal. You are creating your lines by working a filet mesh around the filet mesh of the previous color, but both colors are technically the same row. When you look at the back, there is a different pattern than on the front. It is also Double Thick, whereas Mosaic Crochet is thin.

      Charts for Interlocking Crochet can be used for Mosaic Crochet. However, the same cannot always be said of Mosaic Crochet charts being used for Interlocking Crochet. The rules for Interlocking Crochet are very strict, and Mosaic Crochet can get away with a lot more.

      Please help end the spreading of incorrect information by updating your page. Please remove all references to Interlocking Crochet from any article on Mosaic Crochet. They are not at all the same. Thank you.

    3. I’m not sure Lori…to me a mosaic pattern is very geometric and almost repetitive – you may be able to incorporate a name into a mosaic style design. I honestly do not know where to start with that though.
