Pattern Description
These hexagon motifs are considered to be an Intermediate Skill Level Pattern written in US Terms but can easily be made by a determined beginner with the added help of the video tutorial.
?For this pattern you will mostly be using double crochet stitches while working in the round. You will create chain spaces for the corners of the hexagon to transition to a different side and the center of each side has a double crochet post stitch.
The full crochet hexagons are worked in the round wit no turns and only front post doubled crochet in the center of each side. The half hexagons are worked in rows as we need to turn. On the half hexagons you will alternate front post and back post double crochet in the center stitch of the sides as we are turning the piece and working from the right side and wrong side.
The pattern calls to start with a chain 3 but you may use a magic circle if that is your preferred method for working in the round.
On the half hexagons make sure to always do you increase stitch in the first and last st.
Make as many or as few crochets hexagons and half hexagons so create any size you would like such as a baby blanket, couch throw or afghan for your bed.
You can continue each repeat round to make a very large hexagon if you choose for a more dramatic blanket.
This original design for a hexagon afghan would look wonderful using different colors of scraps or even self-striping yarn!

Yarn Substitutes
Since this pattern is made using worsted weight yarn held double, you have so many options. You can swap for a bulky weight yarn you choose! Be minuful of yardage, you will actually only need half the yardage suggested since you are not doubling the yarn. Here are some of my favored yarns to substitute:
- Vanna’s Choice (Held Double)
- Hue + Me (Bulky, use half the yardage)
- Heartland (Held Double)

Assembly
For this pattern I used the flat zipper seam to assemble my blanket. You may choose to use whichever seaming method you would like. See the photo below for hexagon and half hexagon layout.
- Steam all of your hexis and half hexes before seaming so that your seam does not end up too tight and cause puckering.
- Lay your hexis out like the photo and begin seaming with a flat zipper seam from the bottom left creating a continuous seam for as long as possible.
- A flat zipper seam is created by picking up the back loop of corresponding stitch on the pieces next to each other, drawing up your yarn and creating a slip stitch.
- Once all of your pieces are connected together seam in all of your ends, lightly steam your blanket and you are done!
