Welcome to the first installment of the Mosaic in a Month CAL! If you are just joining in, and need more info about the Mosaic in a Month CAL, read this post.

But I’ll give you a quick summary right here. We are all creating an heirloom geometric crochet blanket together over in the Juniper & Oakes Crochet Community FB Group. Each Monday, Wednesday, and Friday during June 2024, a new free blanket section chart will be released on my blog in blog hop fashion, as there are 10 other designers who helped make this blanket!

The 1st section of the Mosaic in a Month CAL is the Mosaic Triangles section designed by me, Erin of Juniper & Oakes. This mosaic crochet triangle blanket pattern is just one of 12 gorgeous designs that we’ll be making together during June 2024!

This first design features interlocking triangles, made in a simple 12-row repeat that you will memorize in no time. That makes it a perfect project to make while relaxing in the shade.

Instructions

Overlay Mosaic Crochet

This geometric blanket CAL uses the overlay mosaic crochet technique to create each section. This technique is easier than it looks and is super addictive! You’ll need to know how to make foundation single crochet (FSC), back loop only single crochet (BLOsc), and front loop only double crochet (FLOdc), as well as beginning and ending border stitches.

You can learn everything you need to know about overlay mosaic crochet from this blog post, which includes photo and video tutorials for each stitch as well.

Skill Level: Adventurous Beginner/Intermediate

Gauge

23 stitches x 22 rows = 4” x 4” in square
A swatch of the pattern

Size:

Approximately 37” x 53” (the full blanket)

How big will This Section be?

The answer depends on many factors: yarn, hook, tension, etc. If you work a gauge swatch in the pattern stitch and measure it, you can multiply that out to estimate the finished size of your blanket. Mine starts with a foundation row of 195 stitches and is and 21 rows high.

Beginning Border Stitch (BBS)

A standing sc through the post (or the ‘v’) of the stitch below, ensuring that both legs of the stitch on the WS are to the outside of the blanket. (For right-handed crocheters the legs would be secured to the right of the stitch and vice versa for left-handed crocheters.)

Click here for a video tutorial.

Back Loop Only Single Crochet (BLOsc)

Insert hook in back loop of indicated st, yo and pull up a lp, yo and draw through both lps on hook. 

Front Loop Only Double Crochet (FLOdc)

Yo, insert hook in front loop of st below the indicated st, yo and pull up a lp, yo and draw through two lps on hook, yo and draw through remaining two lps on hook.

Ending Border Stitch (EBS)

A sc through the post (or the ‘v’) of the stitch below, ensuring that both legs of the stitch on the WS are to the outside of the blanket. (Similar to BBS, but the back legs of the stitch are secured to the opposite side.)

Notes

• Pattern is worked from right to left on Right Side only.  (If you are left handed, feel free to work from left to right according to the chart below).
• Every row is worked in a different color.
• Fasten off at the end of each row. 
• Every row begins with a beginning border stitch. 
• Every row ends with an ending border stitch. 
• Sc are worked in BLO of the previous row, unless otherwise noted.
• Dc are worked in FLO of stitch 2 rows below, skipping the stitch behind unless otherwise noted. 
• You may choose to repeat the pattern as many times as you wish. Make sure your Foundation Row is made up of any multiple of 48 plus 3 extra stitches. I will be using 4 repeats. So my foundation row is (4×48) + 3 = 195 stitches).
• The patterns include a chart and written instructions below. You may want to refer to each. 
• The colors on the chart indicate how the finished project will look.
• Please join the Juniper & Oakes Crochet Community FB Group and share pictures and questions that arise.

This section was designed in two colors: red and white. But you can choose whatever colors you want!

Get creative! Maybe instead of rainbow colors, neutrals or earth tones are a better complement to your decor. I won’t get offended if you take creative liberties on the color scheme. In fact, I would love to see what fun color schemes you come up with. So share your color combos on the FB group!

The amount of yarn needed depends on different factors like yarn weight, hook size, and tension. Each stripe uses approximately 180 yards of the bright color, plus 173 yards of the white. The blanket has two stripes of each color except for there’s only one violet. So in all, you’ll use about 1900 yards of the white; 320 yards of red, orange, yellow, green, and blue; and 180 yards of violet. Plus you’ll need a little extra for the striped border.
