How to Style the Diamond Crochet Cardigan:

Casual - The Diamond Crochet Cardigan will add a stylish edge to your favorite jeans and flats while out for dinner with your friends and family. For an extra added touch I would add the Herringbone Crochet Clutch so you have a place to put all your essentials.

Dressy - No matter where you are headed, work or date night, a simple boat neck dress with a longer version of the Diamond Crochet Cardigan belted at your natural waist paired with your favorite heels will have you feeling that confidence boost that looks amazing on everyone. To complete your look, I would add the Nettleton Crochet Bag.

Weekend Lounging - the Diamond Crochet Cardigan is cozy enough to wear with yoga pants on the couch while watching your favorite show. Or if changing out of your PJ's isn't appealing, just layer the Diamond Crochet Cardigan over them and enjoy your day! For an added layer of comfort add the Tapestry Arrow Crochet Blanket and the Comfy Cozy Winter Slipper Sock to snuggle up in.

Can I substitute Yarn?

YES!!! But....

I know, I know, you might not like that there is a but. I really do think you probably can substitute, what I don't know is if you are going to be happy with the substitute. Here is how to know if the yarn you want to use will work as a substitute every single time:

🧶Drum roll…..did you do a GAUGE SWATCH. Yep, that dreaded swatch. But listen, it's worth the short time investment. Based on that one small piece of fabric you will know how it will size.

🧶 DRAPE. Okay so this isn't talked about as much. But to me possibly the most important. This will effect the look AND the feel of the piece. If it's a garment, does it move the way you want it to? Is it too stiff? Give it a little jiggle and see if you like the was it lays. 

🧶 FIT. So I might be one of the few designers who will say this out loud but if your gauge is a little bit over (like 1 stitch) just roll with it if you like oversized. This is a way to get a different look out of the garment and who knows, you might even like it more. 

But I don't just talk about substitutes. I like to SHOW you what it might look like. I took my newest pattern and made it with 3 very different yarns. I used:

Shine Sport - cotton yarn (2 weight).

Brava Sport - acrylic yarn (2 weight).

Color Theory Worsted - acrylic yarn (4 weight).
