Introducing the Lexi Tunisian Preemie Blanket: A Hug for the Smallest Miracles

There is nothing quite as tender as crafting for a newborn, especially one who arrives early. The Lexi Tunisian Preemie Blanket is designed to wrap those tiny miracles in a cloud of softness. This pattern utilizes the beautiful Tunisian shell stitch to create a dimensional, wavy texture that is as delightful to touch as it is to look at. Despite its intricate appearance, this is a beginner-friendly project that works up quickly with super bulky yarn, making it the perfect handmade gift for a hospital, a baby shower, or a special arrival at home.

Because it is worked in soft pastel stripes of pink, blue, and white, this blanket is gender-neutral enough for any nursery while remaining classic and soothing. The result is a plush, 20-inch square of comfort that is both durable and breathable—ideal for the delicate needs of a preemie.

Materials Needed

Before you begin, gather the following supplies. Using the correct materials ensures your gauge matches and the blanket comes out perfectly soft and squishy.

  • Yarn: Bernat Baby Blanket Yarn (or any super bulky weight #6 yarn). You will need approximately 220 yards total. Suggested colors: 1 skein each of 'Baby Pink', 'Baby Blue', and 'White'.
  • Hook: Tunisian crochet hook size 10mm (US N/P) with a 12-inch cord. If you don't have a Tunisian hook, you can use a regular crochet hook with a long, smooth shaft, though a stopper at the end is highly recommended to prevent stitches from sliding off.
  • Extras: A yarn needle for weaving in ends and a pair of scissors.

Gauge

To ensure your blanket matches the intended size, check your gauge: 4 stitches and 4 rows in Tunisian simple stitch = 4 inches (10 cm) square. Always make a swatch first to confirm your tension is correct.

Step-by-Step Instructions

This pattern is worked in Tunisian crochet, which is a hybrid between knitting and crochet. Don't be intimidated—the rhythm is easy to pick up. The key is to remember that every row has two passes: the Forward Pass (picking up loops) and the Return Pass (working them off).

Pattern Notes

  • The chain 1 at the start of each row counts as the first stitch.
  • Worked in one piece from bottom to top.
  • The "vertical bars" are the strands of yarn that run vertically on the front of your work after a return pass.

Foundation Row

With Baby Pink yarn, chain 51 loosely. It is crucial to keep this chain loose so the bottom edge doesn't pucker.

Row 1 (Forward Pass): Insert your hook into the second chain from the hook. Yarn over and pull up a loop. Leave this loop on the hook. Repeat this in each chain across. You should now have 51 loops on your hook.

Row 1 (Return Pass): Yarn over and pull through the first loop on the hook (this is your chain stitch). *Yarn over and pull through two loops on the hook.* Repeat from * to * until only one loop remains on the hook. This single loop counts as the first stitch of the next row.

Main Pattern: The Shell Stitch

Now we begin the textured shell pattern. This is where the magic happens. Pay close attention to where you insert the hook—it's into the spaces between the vertical bars, not the bars themselves.

Row 2 (Forward Pass): Chain 1 (this counts as your first stitch). *Skip the next vertical bar, insert your hook into the space between the bars, yarn over, and pull up a loop.* Repeat from * to * across the row. You should have 51 loops on your hook.

Row 2 (Return Pass): Work the return pass exactly as you did in Row 1 (yarn over, pull through one, then yarn over, pull through two until one loop remains).

Row 3 (Forward Pass): Chain 1. *Insert hook into the next space, yarn over, pull up a loop. Chain 1 (this creates a small eyelet). Skip one space, insert hook into the next space, yarn over, pull up a loop.* Repeat from * to * across. This creates the beginning of the wave or scallop effect.

Row 3 (Return Pass): Work the return pass as before.

Row 4 (Forward Pass): Chain 1. *Insert hook into the next space, yarn over, pull up a loop. Insert hook into the chain-1 space from the previous row, yarn over, pull up a loop. Skip one space, insert hook into the next space, yarn over, pull up a loop.* Repeat from * to * across. This fills in the shells, making them puffy and dimensional.

Row 4 (Return Pass): Work the return pass as before.

Color Changes

To create the beautiful stripes, you will change colors after completing Row 4 of each color block.

  • After finishing Row 4 in Pink, change to Baby Blue. To change colors seamlessly, pull the new color (Blue) through the last loop of the return pass. Do not cut the old yarn yet; you can carry it up the side or cut and weave in later. For a cleaner edge, cut and weave in ends.
  • Work Rows 2, 3, and 4 with Baby Blue.
  • Change to White and work Rows 2-4.
  • Continue alternating colors (Pink, Blue, White) until the blanket measures approximately 20 inches in length, ending with a Pink row.

Adding the Border

Once your rectangle reaches the desired length, it's time to finish the edges. Switch to your White yarn for a cohesive look.

Work a round of single crochet around the entire blanket. At each corner, work 3 single crochet stitches into the same corner space to ensure the corners lie flat and turn nicely. This border will tidy up the edges and give the blanket a professional, finished appearance.

Finishing Touches

Weave in all loose ends securely with a yarn needle. Because this is a baby item, make sure to weave in ends thoroughly so they don't come loose during washing.

Finally, block the blanket gently. Since it is made of acrylic, you can lightly steam it (without touching the yarn) or simply lay it flat to air dry. Blocking will even out the stitches and help the shell pattern open up beautifully, enhancing the wavy texture.

Your Lexi Tunisian Preemie Blanket is now complete! This soft, textured, and lovingly made blanket is sure to be a cherished keepsake. Whether you are a seasoned crafter or a beginner looking for a meaningful project, this pattern offers a rewarding experience and a stunning result.
