The Mirabilis Beanie is the ultimate in comfy slouchy crochet hat pattern. With plenty of delicate drape the puff stitch detail feels like pure luxury. A perfect gift to make and give or a cheeky treat for yourself perhaps!

The hat is worked flat with extra short rows for the rib and fabulous puff stitches for the top section to create a relaxed knitted look. 

In 5 sizes from Baby to Large Adult, it also co-ordinates perfectly with a Mirabilis Cardigan to get you set for the season.

How do you make a beanie slouchy?

I’ve found that there are 3 key aspects to making a really good slouchy crochet hat – the stitch, the hook size and the length of the beanie.

  1. The crochet stitch I’ve chosen to use here has a soft and delicate ‘open’ feel to it so that it has lots of drape and therefore doesn’t make the hat too stiff. You want your slouch hat to be a bit floppy and well, ‘slouch’ a bit on the top or the back of your head!
  2. The crochet hook size is important too because it will dictate how the yarn behaves and what the drape is like too. In reality, the stitch, hook and yarn choice create the magic formula in any crochet pattern to give you so many different fabric choices.
  3. Finally, the length of the beanie is also really important. The idea of a slouchy hat is that it has some excess fabric at the top that can flop over the back and so you need to make the hat much longer than you normally would.

As you can see from the images I’m not a fan of a huge amount of slouch and for years I avoided these kind of hats as I felt silly wearing them but I think I’ve cracked exactly the right length for me now!

The great thing about patterns like this is that you can add or take away from the brim length to suit you and make yours as slouchy as you like!

About the slouchy crochet hat pattern

I was lucky enough to be selected to design a pattern for the Fall 2021 Crochet Foundry Magazine and as soon as I had finished my Mirabilis Cardigan pattern I knew I had to make a co-ordinating hat to wear with it!

I had great fun designing the short row rib to make the brim look knitted and you won’t believe the amount of stretch it gives it! The slouchy hat is so comfy to wear and even though it looks quite delicate, it’s really warm too.

The basis of the main stitch means that it’s a puff stitch crochet hat with a lovely deep brim to turn further up or down depending on how you’d like to style it.

The crochet hat is worked flat in a big rectangle that you then seam along the side and gather at the top to form the hat shape and get that all important slouch.

How long should a crochet slouchy hat be?

Well, that’s a very good question. As I said earlier, I don’t much like the really floppy crochet slouch hats (or even ones that aren’t crocheted in fact) so it really comes down to personal taste.

The Craft Yarn Council have a handy head circumference guide but it’s trickier to find standard lengths because of how variable and open to personal opinion it is I suppose.

There is a great chart from Oombawka Design Crochet that tells you some great info about how to make a hat that fits including how long to make them if you’d like it to be a slouch hat.

So a good general rule of thumb is to make a slouchy hat about 2.5cm or 1 inch longer than a regular hat that sits at the base of your ear. Maybe just measure your head and see what you think!

How do you wear a slouch hat?

Another good question that I really had no idea about until I finally decided to design and wear one! It seems that there are many opinions on the subject and the most important deciding factor sees to be your hairstyle.

Until fairly recently I had very short, cropped hair and I found wearing hats quite tricky but I think because I was doing it wrong – if you make sure to wear the slouch hat right at the back of your head and show some of the fringe or sides of your hair it looks great!

If you have longer hair then it looks really nice pulled right down over your forehead and a low ponytail also suits a slouchy beanie really well.

The whole idea of this style of hat is to have a relaxed look so it’s great to just pop it on and do whatever feels comfortable. There’s no right or wrong way to wear one.

What other crochet hat pattern can I make?

If you enjoy making crochet hats then I have plenty for you to choose from! The thing I love most about handmade hats is that they don’t take that much time or yarn to make and so are perfect to whip up as gifts or to sell at craft fairs.

You might like to try out my Walcot seamless chunky hat pattern, my Neo Mint crochet cable stitch hat, or my Slip Stitch beginner crochet beanie pattern. They all use different techniques and are worked from the top down, bottom up and side to side!

If you’re looking for something to make for little ones then you could try the crochet bunny hat, or my pumpkin beanie hat or my basketweave stitch beanie – they are all super quick and easy to make!

Why is the crochet hat worked flat?

I know that lots of people prefer to work crochet hats in the round and not flat but because I was coordinating this one with my new cardigan design I wanted the stitch pattern to run in the same direction and also I really like working hats flat and then seaming them!

I know that might be a surprise to those that know me as I really don’t like seaming anything but for the level of drape and cardigan coordination this ones gives, I’m more than happy to do a bit of seaming!

It also means that there is no increasing or decreasing to worry about. You literally just make a rectangle following the pattern and you’re there.

Tension and sizing options

The slouchy crochet hat comes in 5 sizes from Baby to Large Adult.

The gauge for the hat is 14sts by 10 rows = 10cm by 10cm.

The five sizes, size to fit and the finished hat circumferences are as follows. You’ll see that there is a lot of negative ease (meaning it’s smaller than the head it will go on) but that’s because the stitch pattern is so stretchy. If you find you’d like it a bit bigger then you can just work a few more rows to suit.

SizeTo fit head size (cm)Finished hat circumference (cm)
Teen/Small Adult5442
M/L Adult5846

How much yarn do I need to crochet a slouchy hat?

You don’t need an awful lot of yarn to crochet a hat and so it’s a great project to either raid your stash for (so it’s basically free!) or have a splurge and get some really luxurious yarn!

I chose to use WeCrochet Kindred DK yarn to make my hat and it is perfect for it. The mix of baby alpaca and twist of Peruvian Pima cotton makes it so soft and delicate to work with.

It’s 68% Baby Alpaca, 32% Peruvian Pima Cotton, 115 yds(105m)/ 50g, and I chose the shade Spice.

You’ll need approximately 140 (190, 230, 275, 300)yds of yarn.

A great alternative yarn if you want something acrylic (great to wash for little ones) then I’d go with Paintbox Simply DK – it comes in loads of beautiful colours and is great for you stash too!
