Choose a hook from the fabric it produces with your yarn and technique. A recommended size is a starting point, not a guarantee that your blanket will match someone else’s dimensions.

Start with the pattern and yarn label

Read the pattern’s suggested yarn and hook information, then compare it with the yarn you have chosen. Kathwool’s Acorn Cottage Autumn listing gives several starting ranges for different yarns and asks you to make a measuring sample.

If you substitute a yarn with a different construction or thickness, treat the original hook suggestion as a place to begin sampling. Do not assume that a familiar “DK” label makes every yarn behave alike.

Compare two hooks in the actual stitch pattern

Make the specified panel with your first hook. If you want to compare another size, make a separate panel using the same yarn colors and working method. Label each one immediately.

Measure width and height, then look at the fabric. Are the outlines readable? Does it feel comfortably flexible for a blanket? Can you insert the hook without forcing it? A swatch that reaches the desired dimensions but feels unpleasant to work is not a useful success.

When the sample is the wrong size

The Craft Yarn Council’s gauge guide explains that changing hook size is one way to adjust gauge. For a fixed picture chart, also consider whether the resulting fabric suits the project. Reaching a target width by making an overly loose fabric may not give you the blanket you wanted.

Keep stitch count and row count separate when checking your sample. A hook change can affect both dimensions, but not necessarily by the same proportion.

Keep the working setup consistent

Record the hook size in millimeters.
Note the hook brand or handle style if you own several.
Keep the selected hook with the project.
Recheck your sample if you replace a lost hook with a different model.
Record the yarn and chosen CUT or NO-CUT method with the hook.

The aim is a repeatable setup. Once you have a sample you like and a realistic size estimate, you can begin the blanket with a clear reference instead of repeatedly changing hooks in the main fabric.
