Easy Crochet Study of Blue Blanket Pattern

The Crochet Study of Blue Blanket has been designed for I Like Crochet Magazine for release in October 2025. A magazine focused on just crochet with easy to intermediate level patterns. With over 700 patterns in the magazines it has published in the past, you'll be hooked on this pattern in Fall 2025.

I Like Crochet Magazine wanted a blanket in Mikey's signature look, with a colour palette focused on blue. Mikey selects Caron Colorama in the colour called Overboard. You can create a 56" x 56" square blanket using #5 chunky-weight yarn.

Once the blanket transitions to a square, the remaining part is an easy 4-row repeat until the desired size is reached. This means you could stop when the blanket is big enough for you.

A stitch along for this blanket will come in the future.

The Study of Blue Blanket becomes the 20th Stitch Sampler in the Study of Series by Mikey. You can see all of the study series designs here.

Mikey took a poll on YouTube, and it was determined that more crocheters prefer to let the colours flow from the ball, as is. It breaks Mikey's aesthetic, but the majority ruled this time around. In Mikey's real world, he would have selected different yarn and forced colour changes. This will be up to the crocheters to decide whether to do so.

Yarn Details

Caron Colorama, 180 g/6.4 oz, 208 meters/228 yards

• Overboard - 9 o’gos (1,268 yds)

Hook 6 mm / J/10 Crochet Hook or size needed to obtain gauge.

Gauge 10 sc and 11 rows = 4” [10cm]

Measurement 56” x 56” square. 

Certain areas of the blanket may have benefited greatly from controlled colour changes, such as the popcorn round, for consistency.

Pattern Notes

1. Each Colorama O’go starts with a different colour, but the lengths of the colours are the same. You may want to review your O’gos and arrange them in the order you want the colours to appear. You will crochet without worrying about changing colour with intention. 
2. If a colour is split between the beginning and ending of an o’go, use the entire colour. 
3. In pattern reading. Ch 1 means to physically crochet by chaining 1. If it states ch-1, the instructions use that to place the assigned stitch.

Transition to Square

Prepare the next round with stitch markers to locate the corners. Use the first stitch as the first corner and place a stitch marker. [Starting in next st, count to the 70th st and mark with a stitch marker.] 3 times. 

When counting the stitches per side, don’t include the chain spaces that make up the turn of a corner. 

Additional Tip: Joining with hdc means to use hdc to reach over to the first stitch to create a bridge, which equals ch-2. Use the post of that hdc created as a ch-2 space.
