I have now made quite a few of these sets since taking the classes on them in October and November at The Yarn Connection. The weight of the yarn does indeed do matter. The sets I made for my girls are made of a thicker yarn and while the girls love them, I think they are a little big. Of course it doesn't help that they like to wear the headbands forward more like a hat. LOL I do however absolutely LOVE the way the thicker yarn makes the cables really stand out on the neckwarmer. I used Lion Brand Hometown USA yarn for these.
I made this set for Siobhan otherwise known as The Mama Monkey. These are so quick & easy to make. I used Loops & Threads Charisma yarn for this set. The buttons are handcrafted by a local artisan and look so gorgeous on against the cream color of the neckwarmer.
This one was made for the wife of my one my hubby's coworkers. She wanted just the neckwarmer. I have also made a headband for my mom recently but forgot to take a pic of it before mailing it off. LOL I also used Loops & Threads Charisma for this one. The buttons are from Michael's. It's hard to tell in the pic, but they go perfectly with the color of yarn. The buttons are a lighter shade of purple with with lavender/pink flowers. The pic really doesn't do them justice.
