Crochet Geometric Design – Interlocking crochet – Double Filet Crochet – Intermeshing Crochet

I have once again been experimenting with geometric designs using the technique of intermeshing –double filet crochet. The inspiration for the above design came from the chart below, which I found in a box of old charts. I think it was a machine knitting chart at one time.

In my opinion, the experiment has turned out very well, and I intend to use the design to make an Afghan. But I think this would also be a great design for a throw cushion/pillow.

My sample swatch measures 19.5” X 13” I used a crochet hook and DK yarn left over from a previous projects. Unfortunately, I ran out of black yarn and had to substitute navy yarn in order to complete the design.

This design is reversible.

Crochet Sample Swatch – Interlocking crochet – Intermeshing Crochet – Double Filet Crochet


This is my latest chart experiment. I can’t remember where I first saw this design, but I used it to make a knitted shopping bag some years ago. Recently, I came across the design again and decided to make another bag, but this time using the technique of intermeshing crochet/double filet crochet, as I thought this would produce a more sturdy bag.

Original chart

I used the original to created an amended chart that I could work from, but I deliberately omitted the first and last cell of each row of the design from my swatch, as I was not sure that I would have enough yarn to complete the design.


Amended Chart

The basic design was quite easy to tweak and the resulting swatch, which although much chunkier-looking than the original knitted version, is very nice. I have now decided not to make the shopping bag, but thought I would share the sample swatch with you.

Crochet sample swatch – Interlocking crochet – Intermeshing Crochet – Double Filet Crochet


This lovely design was adapted from a small piece of hideous gold and black coloured 60’s/70’s wall paper, that I recently discovered while stripping a wall. Apart from the colour, the design is almost exactly the same, although the shapes on the wallpaper tended to be a bit more pointed. Interlocking Crochet /Intermeshing Crochet /Double Filet Crochet is based on cells/boxes, therefore sharp pointed shapes are usually only seen on the back of the fabric(side B). The fabric is reversible.


The design is almost a collection of diamonds. In fact, in order to create a chart to work from, I placed three diamond shaped charts end to end. Then, I made slight changes to the size of each part of the design, by adding and removing cells where necessary in order to make smaller motif fit.

ColBchart            ColAchart

Once worked out, the design was very easy to follow and I think it turned out pretty well.


To make my sample motif:
Yarn Type: Unknown amounts of Double knitting yarn, left over from a previous projects, in colours Blue and White.
Needles: 4.00mm crochet hook.
Method: Work a foundation row of 31 cells in colour A and 30 cells in colour B, and follow the charts.

Sample swatch Houndstooth design – Interlocking crochet – Intermeshing Crochet – Double Filet Crochet



I have been trying to come up with a design that looks like houndstooth, using the technique of intermeshing crochet / interlocking crochet. Some of my results have not exactly come close to true houndstooth, but this one is pretty good, so I thought I’d share it!
As usual for intermeshing crochet, the fabric is reversible. However, there are two different designs, one on each side of the swatch.

I found a really good tutorial on how to weave the simplest version of houndstooth known as pinwheel and puppytooth
I then created a chart based on the woven cloth to work from. I did not realise that I had reversed the motif, until after I had worked the swatch!



I also created a chart for a larger version of the design…

I think the larger version of the design would be great on a blanket/Afghan.

This sample is worked over 32 cells col A , 31 cells col B, in 4 ply acrylic using 3mm hook, and measures 8” X 7” (not blocked). Should I work this design again, I think I will use a larger hook, as I tend to work quite tightly.

Edging Motif – Intermeshing Crochet – Double Filet Crochet – Interlocking crochet


I am currently working on a design idea for another Afghan using the technique of Intermeshing Crochet/Double filet Crochet/Interlocking Crochet; I prefer this technique as it produces a totally reversible fabric which is perfect for Afghans or Blankets.

In my yarn stash I have a full cone of 4 ply machine knitting yarn in what the label describes as caramel colour. However, it looks more like a pinky beige. Not the most exciting colour I’ve seen, and it will really need a bold design to liven it up. I think a chocolate/cocoa brown colour would be most appropriate for the second yarn colour.

I had an intended to try a “Greek key” type design as a surrounding edge to a less formal inner main body design for the Afghan. I have not got very far with the design for the main body as yet, but I have decided not to go with the Greek key idea. Instead, I’m going to use the “cross” part of a “noughts and crosses” design I have also been working on for some time as the surround ( most of the time I have a few design ideas either partially executed or floating around in my mind) …..


The basic chart used for the “X” motif…..


Each individual motif is worked over 9 cells (10 dc’s).

Obliviously, you will need to multiply the number of motifs in accordance with the size Afghan required. But as the intended surrounding edge, it would look something like this…………


Now, all I have to do is come up with a design idea for the main body of the Afghan!

Rhapsody Afghan – Intermeshing Crochet – Double Filet Crochet – Interlocking crochet


The inspiration for this Afghan came from a knitting chart I found at

I came up with many variations on the basic design and it took quite some time to decide which variation I would finally use.
Once I had made a decision about the design I had to create a chart to work from (I hate writing patterns… they go on forever).
I use a computer spreadsheet to create my charts and once created, the charts often require tweaking in order to make a particular design work in yarn.

What I mean by “tweaking” is that I make amendments to the original design chart (I call them “tweaks”).

I print a copy of the chart and mark my tweaks on the copy as I work through a sample of the given design (I always work a swatch). I am unable to show these amendments/tweaks on the chart due to the limitations of my computer software.

In this instance, as can clearly be seen, the number of cells in the “L” shapes of the finished design is 6 across and 6 up or down. However, the chart shows 5 across and 6 up or down. The same goes for the number of cells separating the “L” shapes, in the finished design there are 11 cells. However, the chart shows 9 cells.


Side B

The design: Worked over multiples of 8 cells plus 1
Afghan measures: 66”x 41” (not blocked)
Yarn Type:1 cone of 4 ply Acrylic machine knitting yarn in Black and 1 cone of 4 ply Acrylic machine knitting yarn in Denim.
Needles: 3.50mm crochet hook.

Teddy bear sample – Interlocking crochet – Intermeshing Crochet – Double Filet Crochet



I found this chart on and thought that it could be used with the technique of intermeshing crochet – double filet crochet. The chart was quite easy to follow with a little tweaking. However, the results were not as expected.




The bear’s face is unusually long, thin and quite grumpy looking. I have also knitted this chart, resulting in a much more rounded and friendly looking face for the bear. This suggests that shorter stitches produce a much better outcome.




I think that the results would suggest that this chart is unsuitable for use with this technique – You can’t win them all!

Happy holidays!
