The Free Botanical Brew Crochet Pattern
The Botanical Brew Crochet Summer Blanket
The Botanical Brew is a free crochet summer blanket pattern filled with soft color and open texture. Staggered eyelets move gently across the fabric, giving the lightweight throw an airy quality that feels well suited to the warmer months.
Three-row stripes of botanical color alternate with narrow bands of soft neutral yarn. This allows each shade to hold its own place within the blanket while still becoming part of the larger color story.
The free pattern creates a light summer afghan that is warm enough for cooler evenings without feeling heavy. Draped over a chair, folded at the end of a bed, or carried outdoors at summertime, it brings the colors of the garden into a useful everyday blanket.


How To Crochet A Lightweight Summer Blanket
This free blanket pattern uses 24 different colors of fingering-weight yarn, along with a soft neutral shade. The original was made with Peruvian Highland wool that I hand-dyed through solar dyeing, using flowers and plants gathered from the landscape around me.
The beginner friendly crochet pattern alternates three rows of color with two rows of neutral yarn. Staggered eyelets are worked across the blanket to form a delicate, open texture. The thin yarn and narrow stripes help the finished summer throw remain light and airy.
Naturally dyed yarn is not required for the free pattern, making it easy to choose from the mini skeins already in your collection. Select 24 varied colors inspired by nature to create a similar effect, or arrange your own palette to give this easy crochet blanket a different seasonal feeling.
Free Crochet Pattern: Botanical Brew Blanket
Pattern Information:
About:
The Botanical Brew Blanket began with 24 mini skeins of fingering-weight Peruvian Highland wool that I hand-dyed using a process called solar dyeing. Using natural plant materials and the warmth and light of the sun, I created a collection of soft botanical colors. Many of the flowers and plants I gathered for the dyes were especially meaningful to me.
The blanket alternates three-row botanical stripes with narrow two-row stripes of a soft neutral. Staggered eyelets travel across the fabric, creating an open, delicate texture while allowing each individual color to stand on its own.
The original Botanical Brew Blanket was made with naturally dyed yarn, but naturally dyed yarn is not required. You will need 24 different colors or 24 fingering-weight mini skeins to create the striped design. To achieve a look similar to the original blanket, choose a collection of soft, varied colors inspired by nature.

Pattern Notes:
The blanket is worked flat in rows, turning at the end of each row.
The foundation row counts as the first of the three rows worked in Botanical Color 1.
The body of the blanket contains 118 rows before the border:
- 72 botanical-colored rows
- 46 Pale Mushroom rows
The ch-3 at the beginning of a double-crochet eyelet row counts as the first dc.
The ch-1 at the beginning of a row does not count as a stitch.
Maintain 256 sts throughout the blanket. Each ch-2 space spans two stitch positions and replaces the two stitches skipped beneath it. When working the following solid row, work 2 sts into ea ch-2 sp to restore those two individual sts.
The two eyelet rows are offset by four stitch positions, creating the staggered-eyelet design.

Along each side edge, work dc evenly into the ends of the rows, spacing the stitches so the border lies flat. At each remaining corner, work 3 dc in the corner stitch or space. Join with a sl st to the top of the beginning ch 3. Fasten off and weave in ends.
Finishing + Blocking:
Soak the finished blanket in lukewarm water with a small amount of wool wash. Gently remove excess water without wringing, then roll the blanket in a towel to absorb additional moisture. Lay flat, shape to finished measurements, and allow to dry completely. Weave in loose ends.
