How to Crochet


Why are there different crochet hook size systems?

Different regions around the world developed their own crochet hook sizing systems over time, leading to the variety we see today. This diversity reflects the rich history and global nature of crochet.

What if my crochet hook doesn’t have a size label?

If your crochet hook doesn’t have a size label, you can use a hook gauge to determine its size. These tools have holes of various sizes that you can insert your hook into to find its match.

What is a swatch test in crochet?

A swatch test involves crocheting a small square with the hook and yarn you plan to use for your project. This helps you determine if you’re achieving the correct gauge as per the pattern.

What is gauge in crochet?

Guage refers to the number of stitches and rows in a specified measurement (usually 1 inch or 4 inches). It’s crucial for ensuring your finished project matches the size specified in the pattern.

What should I do if my gauge doesn’t match the pattern’s gauge?

If your gauge doesn’t match the pattern’s gauge, try adjusting your hook size. If your stitches are too large, try a smaller hook. If they’re too small, try a larger hook.

Is there a standard crochet hook size for beginners?

There’s no standard size, but many beginners find it easier to start with a medium-sized hook, such as an H/8 (5mm) hook.

What material is best for crochet hooks?

The best material depends on your personal preference. Aluminum hooks are durable and slide easily through yarn, while bamboo hooks are lightweight and warm in the hand.


Crocheting is a journey of creativity and patience, a dance between the hook and yarn. While the diversity of hook sizes and systems may seem daunting, remember that every knot, every stitch, is a step towards mastering this beautiful craft.

With our guide, you’re well-equipped to navigate the sea of loops and stitches. So, here’s to happy hooking and blissful crocheting!

Afghan Sizes – Choose the Right Blanket Size for Your Bed

Choose the Right Blanket Size for Your Bed

Welcome, cozy comfort seekers! Whether you’re snuggling up for a Netflix marathon or settling in for a restful night’s sleep, the right blanket can make all the difference. It’s not just about the fabric or the pattern – the size matters too! Choosing the perfect blanket size can be a task, especially when it comes to the diverse dimensions of Afghan blankets.

When we think of an Afghan blanket, what comes to mind are intricate patterns, gorgeous colours, and above all, warm comfort. Originating from the rich textile culture of Afghanistan, these blankets have found a special place in homes worldwide, loved for their versatility and style. However, when it comes to choosing the perfect Afghan size for your bed, things can get a bit tricky.

The various sizes of Afghan blankets correspond to different uses and beds, adding an extra layer of warmth to everything from your single day bed to your luxurious king-sized retreat. So how do you pick the right size for your needs?

A handy reference from information collected over the years from the internet, various publications, patterns, first hand knowledge, etc.

The sizes given are intended to just cover the top of the intended item or recipient, plus a couple of inches extra. You’ll need to make it larger be adding extra squares on three of the four sides, or go up a size, to allow extra for hanging over the side, tucking in, etc.

I’ve also added a quick reference for the number of knitted or crocheted squares in the most common sizes for each size afghan. Where the number of squares does not work out exactly, the number given will make a slightly larger item than given under Measurements.

In brackets is the arrangment of the squares, ie 48 (6×8) means that particular size takes 48 squares, and they should be assembled 6 columns across (in width) by 8 rows down (in length).

Note: The bed sizes are based on Canadian measurements. Elsewhere in the world, they may be somewhat different.
