Crochet Pattern: Expanding Pentagon Motif

By Amy Yarbrough – 27 Comments
Have you ever tried crocheting a project with motifs of shapes other than squares? It can be challenging, especially when you’re not following an already made pattern. But it’s also a lot of fun. Here’s an elegant but simple pentagon motif that is very versatile. Choose to make it smaller by crocheting less rounds, or larger by following the same increasing method, whichever best suits your project. Expanding Pentagon Motif

Skill Level:

Finished Size: 3 1/4″ (8 cm) in diameter

Light Weight Yarn (approximately 15 yards)
Crochet Hook B (2.25 mm)

Round 1 measures 3/4” (2 cm)

Crochet Pattern: Expanding Pentagon Motif
Round 1: make an adjustable ring, ch 3 (counts as 1 dc now and throughout), 14 dc in ring, sl st in top of beginning ch-3: 15 dc

Round 2: ch 6, dc in same dc as last sl st, *dc in next 2 dc, (dc, ch 3, dc) in next dc, repeat from * 3 more times, dc in next 2 dc, sl st in third ch of beginning ch-6: 20 dc

Round 3: (sl st, ch 3, dc, ch 3, 2 dc) in first ch-3 space, *dc in next 4 dc, (2 dc, ch 3, 2 dc) in next ch-3 space, repeat from * 3 more times, dc in next 4 dc, sl st in top of beginning ch-3: 40 dc

Round 4: sl st in next dc, (sl st, ch 3, dc, ch 3, 2 dc) in first ch-3 space, *dc in next 8 dc, (2 dc, ch 3, 2 dc) in next ch-3 space, repeat from * 3 more times, dc in next 8 dc, sl st in top of beginning ch-3: 60 dc

Finish off or continue increasing in this manner until motif measures desired size.

    I would like to make hexagons over the summer using up all my scraps. Then this Autumn when it’s cooler, join them for an afghan.

  2. jean says:

    This looks very doable for me. Do you by any chance have a pattern for an expanding hexagon or 8 sided motif?

  3. Emma says:

    I really love this hexagon “expandable” design. I’m a fairly new crocheter and have gone nuts making all sorts of things. Can’t get enough! I wanted to do this to cover the top of a large square coffee table in our den that’s been damaged by dogs and kids over the years. Husband says that the hexagon “won’t work” for this table, though. Says it “has” to be square. Is there a way to do this expandable motif to be a table cover…only square? Please?

    hi like this. could this be used to make an owl motif ?????? x

  5. Hi Sian, I’m sure it could! What a wonderful idea. But if you want a different shape you could read the latest blog, Expanding Geometric Motif Crochet Tutorial, and learn how to make any shape.


  6. Angie says:

    Just found your site. Thanks for sharing this pattern. I’ve been looking for a pentagon pattern for quite awhile and this is just what I wanted.

  7. Alice says:

    I keep winding up with 16 DC in the second round. Any ideas?

    • Hi Alice,

      Do you have 15 dc on the first round? In each corner you are basically increasing once (5 increases) so that you have another 5 sts to add to the first round. Are you sure you are increasing each time?


  8. Tammy says:

    Can you help? I want to make this into a star once I get to the size I want. How can I make each section into a point?

    • Amy says:

      Hello Tammy,
      It will depend upon how prominent you want the points to be. I would suggest building with taller stitches at each point until you get the shape you want.

      Happy Crocheting,

  9. Tammy says:

    My thought is to make 2 pentagon then add points to form a star shape then make 2 and sew together to make a type of cocoon for a baby I think I need to do each section and decrease my way out to a point.

  10. Tammy says:

    I don’t know why but by round 6 it is starting to get wavy. I thought baste on your pattern round 2 ended with 20 round 3 ended with 40 round 4 ended with 60 so of course my thought is round 5 end with 80 and so on ugg I’m not good with this stuff.

  11. Amy says:

    If you are having trouble I might suggest finding a pattern similar to what you have in mind and referring to it for help. It’s difficult for me to instruct you on an idea without working it all out myself first. Sorry I can’t be of more help.

    Hope it works out for you!

    How to do this pattern with no holes?

    • Amy says:

      Hello Tatyana,
      What an interesting concept! I suppose you could work the same number of double crochets in place of the chains. Like for example in Round 2 when it says “(dc, ch 3, dc),” simply work 5 dc.

    This is the simplest and best crochet pentagon pattern ever. I am going to join together to make a football shape stitched to a blanket to make a pyjama case.
