The Summer Nights Crochet Blanket Pattern

How to Crochet the Summer Nights Blanket

Hi guys! The Summer Nights Blanket is inspired by those perfect summer evenings when the sun doesn’t set until 9:00 pm; the smell of bonfire is wafting through the air; and you can be found curled up with a good book and a refreshing drink. Crocheters of any level will love this blanket because the double crochet stitch is soothing to work, and the large crochet hook helps it work up quickly. The loose stitches create a light and airy blanket that is perfect for the warmer weather. Did I mention that the colour combinations are endless? I hope you have fun getting creative with colour. Let’s get started!

The Evolution of the Painted Arrow Blanket

This blanket started out as a shawl that I set aside a few years ago because I didn’t know how to type up a written pattern. During the quarantine, I came across this shawl while I was sorting through my yarn and half-finished projects; I fell in love with the triangle stripes and the mixture of dark and bright colours, but I wanted it to be more than a shawl. I’m a firm believer that you can never have too many blankets, so I set to work on transforming this shawl into a blanket. Using a large crochet hook, I was able to finish crocheting this piece in 4 days, and I’ve been cuddling with it ever since.

Making Adjustments to your Blanket:

  • Width: The original blanket is 44” wide. To adjust the width of your blanket, continue repeating Row 3 until you are satisfied with the width of your blanket; then proceed to the instructions for Row 21.

I’ve included a diagram of each stage of the blanket below, so that you are not surprised by the shape of your blanket as you work through the pattern. Instructions will be provided to show you how to increase and decrease.

1. Each panel starts out as a small triangle, that increases along the three sides shown below (center, bottom left, and bottom right).

2. When the base of the triangle (width of the rectangular panel) reaches 44″, the width will no longer increase, but the length (height of triangle) will continue to increase.

3. Once the height of the triangle (from base to tip) measures 69″, the length of the blanket will no longer increase.

Crochet Blocking with Straight Pins

Fasten off and weave in ends!

Block your Work (Do NOT Skip this Step):

Blocking your work is usually optional, but it is essential for this piece. Blocking your work is done by wetting or steaming your crochet piece to allow the stitches to relax, stretch out, and lie flat.

Steam Blocking a Crochet Rectangle

Steamer/Iron Method: Lay your piece flat or vertically (depending on how your steamer works) and move the steamer/iron over your work. Make sure that the steamer/iron is at least 2 inches away from your work. Pull on your piece to straighten it out, and let it dry. Pin and Spray Method: If you don’t have a steamer or iron, you can use straight pins to stretch and straighten out your work, before lightly spraying it with water. Allow the piece to dry overnight or wait 24 hours before unpinning it.

Border:

I felt like the Summer Nights blanket needed a border to keep the edges of the blanket straight and secure, so while a border is optional, I highly recommend adding it to your blanket.

The border will be worked along the outside edges of your blanket. Make sure that your blanket is facing the right side (RS) before you start your border.

The border will be a moss stitch/linen stitch border. This means that we will be single crocheting in a stitch/row (along the outside of the blanket), chaining 1, skipping a stitch, and working a single crochet into the next stitch. Here is a great video tutorial for the moss stitch border by Blossom Crochet. Keep in mind that a single crochet (US term) is called a double crochet in the UK.

Tip: To make the border even, don’t place the single crochets too close OR too far away from each other. The first row of the border sets the tone for the remaining rows. Try to be consistent with where you are placing your single crochet stitches.

Round 1: With Colour A, make a standing single crochet in the center ch-2 sp. Ch 1, sk a st/row, and make a single crochet in the next st/row. Repeat this process along the edge of your blanket until you reach the corner. Make a (sc, ch 2, sc) into the corner of your blanket. Repeat the moss stitch pattern along each side and corner until you arrive at the first stitch of the round. Join the last st to the first st with a slip stitch to close the round. Do not turn your work.

Round 2: Ch 1, sc in 1st ch-1 sp, [ch 1, sc in next ch-1 sp] repeat across each side of your blanket. Work a (sc, ch 2, sc) in each corner ch-2 sp of the previous round. To join, sl st into the 1st st of the round. Do not turn your work.

Round 3 – 4: Repeat Round 2. Fasten off and weave in ends.
