Learn How To Crochet The Interlocking Block Stitch (aka Plaid Stitch)
If you are looking for a solid and versatile stitch for your project that looks beautiful from both sides, the interlocking block stitch is the one for you.
The interlocking block stitch is sometimes known as the plaid stitch because, when crocheted by alternating three colors, it gives a wonderful plaid effect to your work.
I used this colorwork to create Baby’s First Christmas Blanket, you can find the free pattern HERE.

About The Interlocking Block Stitch
My tutorial shows you how to crochet this stitch using three colors, but you can use as many or as little colors as you like.
You can use the interlocking block stitch to create beautiful, intricate colorwork designs or keep it simple by using just one color and it will look just as beautiful.
When alternating three colors, as I did in Baby’s First Christmas Blanket, the color changes are seamless and you don’t need to cut the yarn after switching.
Isn’t that wonderful? No eds to weave in!

Most basic stitches below have a video that shows you how to crochet them. Follow the blue link next to them for each individual video.
Long SC / Long HDC / Long DC: These stitches are a variation on the traditional ones. The only difference is that they are crocheted one row below the usual one.
The below example shows how the double crochet stitches in green are crocheted one row below into the white stitches, making it a long double crochet.

Interlocking Block Stitch – Written Tutorial
The pattern consists of a repeat of 2 rows while you also change the colors. The order of which I alternated the colors was green, white, red, feel free to experiment with your own color combinations and use as many colors as you like.
With 6.5mm hook and green yarn chain 24 or any multiples of 6 chains.
Row 1: dc in 4th ch from hook, dc, *ch3, sk3, 3dc*, repeat ** until the end of the row.
Change colors to white and turn.
Row 2: ch3, sk3, *3 long dc, ch3, sk3*, repeat until the end of the row, sl st.
Switch to red and turn.
Row 3: long sc in the very first stitch, ch2 (counts as the first long dc), 2 long dc, *ch3, sk3, 3 long dc*, repeat ** until the end of the row.
From this point on, repeat Rows 2 & 3 (not forgetting to alternate the 3 colors) until you have the desired length and are ready to crochet the final row.
Make sure the final row in the blanket will be crocheted in green.
Final Row: sc in the very first stitch, 2sc, *3 long hdc, 3sc*, repeat ** until the end of the row, don’t turn, don’t cut the green yarn.
Now you can crochet a single crochet border around your work to hide the color changes made on both sides. You can see how I did it AT THE END OF THIS VIDEO.
