How to Choose Your Blanket Size
Before you start your blanket, it’s important to decide what size you want to make, and make sure your foundation chain will give you the right width.
Here’s a simple step-by-step guide to help you plan:
Step 1: Choose Your Blanket Size
Decide on the finished size you want. Are you making a lap blanket, a throw, or a full bed-sized blanket, like twin, queen, or king ?
Step 2: Make a Gauge Swatch
A gauge swatch helps you figure out how many stitches you need for your specific yarn and hook. Here's how:
1. Chain 12 stitches.
2. Work 6 rows of half double crochet (hdc), with 1 hdc in each stitch.
3. Fasten off and measure the width of the swatch.
Step 3: Use the Swatch to Calculate Your Starting Chain
Once you know how wide your swatch is, use the chart below to find out how many chains you need for your chosen blanket size.
Example Starting Chains Based on Gauge Swatch
Gauge Swatch Width : 2.5" / 6.3 cm
Blanket Size : Twin
Approx. Dimensions (cm/in) : 63" x 95" / 160 x 240 cm
Starting Chain : 290 chains
Gauge Swatch Width : 3" / 7.6 cm
Blanket Size : King
Approx. Dimensions (cm/in) : 108" x 100" / 275 x 255 cm
Starting Chain : 398 chains
These sizes do not include a border. Your final size may vary slightly depending on your personal tension and crochet style.
Sizing Tip:
If you're using a larger hook or thicker yarn, you may want to:
Make a larger gauge swatch
Adjust your chain count using the chart
Or make two smaller blankets instead of one large one
This will help keep your blanket comfortable and not too bulky.
How to Start Your Shell Stitch Blanket
Once you've figured out your starting chain, it's time to begin your blanket!
Foundation Row (Traditional Method for HDC Blankets):
1. Make a slip knot on your hook.
2. Chain the number of stitches needed for your blanket size.
3. Add 2 extra chains , these are your turning chains.
4. Work 1 half double crochet (hdc) into the 3rd chain from the hook.
5. Continue with 1 hdc into each chain until the end of the row.
That’s your first row done! You can now simply follow the rest of the pattern as indicated below, alongside the switch diagram.
