Tunisian Crochet Blanket CAL 2021 – Square #25

Welcome to square #25 of the Tunisian Blanket CAL of 2021! This is a bonus square that I designed since I wanted to add another block to my blanket to make it a square (5 x 5). This block is made up of a combination of Tunisian Simple and Purl stitches, and the instructions are very easy to memorize. Continue reading for the details of this square and for the pattern.

Square #25 – Tunisian Ridges Square – designed by Arunima from Knitter Knotter

The Tunisian Blanket CAL of 2021 consists of 24 blocks but I wanted to add another one to make mine into a 5×5 blanket. Since this was going to be my last square, I wanted to it to be an easy stitch pattern that I didn’t have to focus too much on. This block is made up of a combination of simple and purl stitches, and the instructions are very easy to memorize. The final pattern is beautiful and has great texture, which I think would be great for a blanket!

Here is my square – I made it with 4 colors of the Wool of the Andes Superwash yarn by KnitPicks.

What you will need (with clickable affiliate links)

  1. Yarn: Worsted weight yarn, I used Wool of the Andes Superwash by Knit Picks in colors Amethyst Heather, Brass Heather, Cobblestone Heather and White. It used about 110 yards (100 m) of yarn and weighs 1.75 oz (50 gms).
  2. Hook: 8 mm Tunisian crochet hook, 6.5 mm crochet hook for the border (optional)
  3. Scissors
  4. Measuring Tape
  5. Tapestry needle to weave in tails

Experience Level



6 rows of 8 Tunisian Simple Stitches is a 2 inch square.


  1. ch – chain
  2. fs – First Stitch – Skip the first vertical bar of the previous row (the one right under the one on the hook). The loop on the hook will count as the first stitch for every row. 
  3. ls – Last Stitch – Pick up the two vertical bars of the last stitch of the previous row, yarn over, pull through both the vertical bars into a loop on the hook.
  4. tss – Tunisian Simple Stitch– Insert hook in the vertical bar, yarn over, pull up a loop on the hook. 
  5. tps – Tunisian Purl Stitch – Bring yarn forward, insert hook into the vertical bar, yarn over, pull up a loop on the hook.
  6. FP – Forward Pass
  7. RP – Return Pass


C1: Amethyst Heather
C2: White
C3: Brass Heather
C4: Cobblestone Heather

In my block, I’ve made the first 15 rows with C1, the next 4 rows with C2, the next 15 rows and the bind off row with C3. I then made a single crochet border with C4.


To adjust width – add or remove stitches in multiples of four.
To adjust length – add or remove rows as needed.

Pattern Notes

  1. This pattern is written in English / US terms.
  2. See Colors section for the colors used in my block.
  3. The instructions below are only for the forward pass. The return pass for every row is the same: 
    • ch1, (yo, pull through two loops)* all the way till the end of the row.


Foundation Row: 
With C1, chain 38 (multiples of 4 plus 2). Make the foundation row stitches in the back loops of the chain. 

Row 1:
fs, (4 tss, 4 tps) * until the end of the row, ls

Row 2:
fs, (4 tps, 4 tss) * until the end of the row, ls

Rows 3 – 33:
Repeat Rows 1 and 2 until Row 33 or until desired length is achieved.

Row 34:
fs, (4 tps, 4 tss) * until the end of the row, ls
This will be the bind off row. You will make a slip stitch every time you pick up a loop on your hook. There is no return pass for this row.


I recommend blocking the square using your preferred method of blocking before joining with the rest of the squares to make a blanket. 


In my square, I made a border with a 6.5 mm hook using the following pattern:
Single crochet in each edge stitch, make 3 single crochet stitches in the corners.

I used the stitch markers from Walnut Farm Design to keep track of my stitches and I wet blocked my square by soaking it in warm water and pinning it to my blocking mat until dry.

No one else can make a full tutorial of the pattern unless permitted by the designer. I have included my notes and links to my tutorials that I think might be helpful in making the square but those do not supersede the instructions and tutorials provided by the designer.
