How to Single Crochet a Pentagon

Today, I’d like to share with you my single crochet pentagon pattern.

There are several ways you can go about crocheting a pentagon, mostly using double crochet stitches.

However, while double crochet pentagons are mostly useful for blankets, garments, and other accessories, a nice, solid pentagon in single crochet can be very handy for all sorts of Amigurumi and home decor projects.

There was a little bit of trial and error to get to the perfect formula to crochet a pentagon in single crochet, and you’ll see that the pattern is not a simple repeat of one round all the way.

Instead, it’s a combination of two different increase patterns with an interesting repetition every 4 rounds.

To make things easier, I’ll first share the pattern up to round 18. Then, I’ll guide you through the logic of the pattern, so that you can continue behind round 18 if you need to.

Single CROCHET A PENTAGON – Pattern Explanation

Now that you saw the pattern, you might wonder why I used two different kinds of increase patterns:

• One increase pattern is the one that we first saw for round 3, where the increases were done with a [sc 3] at each corner.
• Then, there is the other method where the increases are done with a single crochet increase at each corner, like in round 4.

Let’s take a step back.

When I first made a pentagon, I used a much simpler pattern, which we will call “WRONG Pentagon”, that went like this:

Round 1. Sc 5. (5 sts)
Round 2. [Sc 3] in each st around. (15 sts)
Round 3. (Sc inc 1, sc 2) 5 times. (20 sts)
Round 4. (Sc inc 1, sc 3) 5 times. (25 sts)
Round 5. (Sc inc 1, sc 4) 5 times. (30 sts)
And so on…

Very easy to remember and the pentagon looked like the one below.

You might notice that this pentagon was kind of working, it wasn’t very pointy at the corners but it was a pentagon!

With the exception that this pattern can only work well up to rounds 6 or 7 before it won’t lay flat. You can try it for yourself if you want. At some point, you’ll get a sort of dome.

The reason? The stitches don’t increase enough!

So, I made a nice table where I compared the stitch counts of a single crochet circle with the stitch counts of my WRONG Pentagon.

From there, I realized that every 4 rounds, it needed to have 10 increases instead of just 5. And to obtain that, every 4 rounds, I inserted a round where the increases are made with a [sc 3] at each corner.

	RIGHT Pentagon	Sc Circle	WRONG Pentagon
Round 1	5	6	5
Round 2	10	12	15
Round 3	20	18	20
Round 4	25	24	25
Round 5	30	30	30
Round 6	40	36	35
Round 7	45	42	40
Round 8	50	48	45
Round 9	55	54	50
Round 10	60	60	55
Round 11	70	66	60
Round 12	75	72	65
Round 13	80	78	70
Round 14	85	84	75
Round 15	90	90	80
Round 16	100	96	85
Round 17	105	102	90
Round 18	110	108	95
Round 19	115	114	100
Round 20	120	120	105
Round 21	130	126	110
Round 22	135	132	115
Round 23	140	138	120
Round 24	145	144	125
Round 25	150	150	130

If you take a look at the table, you’ll see that the stitch counts don’t correspond exactly for each round. However, with the right pentagon pattern, every 4 rounds, you have the same stitch count as for the simple crochet circle.

After each one of those rounds where the stitch counts are the same, you need to increase with the [sc 3] at the corners instead of a sc inc.

Then, make 4 rounds with a sc inc at the corners, and so on.

I hope this makes sense!
