Today I have been making swatches for my Playing with Triangles Shawl class this weekend at the Longmont Yarn Shoppe. These are to show my students what a difference changing the size of hook can make to your fabric. I used Ella Rae Cozy Worsted for my swatches.
Swatch #1 I used a 4.5mm size hook. Swatch #2 I used a 5.5mm size hook. Swatch #3 I used a 6.5mm size hook.
I think I will make a fourth swatch, since I wasn’t completely happy with how the fabric came out in swatch #3. I’m actually going to go down half a millimeter in size to see if I like that fabric better.

This is one of the things I love about crochet – it can turn out so different with just the slightest change of hook size or yarn type. It’s brilliant!
This is an excellent thing to go over with students – when I first started crocheting I didn’t think that it mattered that much if it was just a few mm off – needless to say I had some very interesting textured/shaped blankets – not interesting in a good way! LOL
LOL! Yes, sometimes we have to learn by our projects going a bit awry. I hope you kept those projects or at least photos of them, that way you can look back and appreciate how much your skills have grown.
Oh my, most of those were long before you could take pictures with your phone. The images are burned into my brain though LOL!!
