One of the types of yarn I enjoyed using was the Red Heart reflective yarn. Here is an example of my using it as a contrasting band in a hat.
I've also used it in entire hats, as well as to make high-visibility wrist bands.
Unfortunately, none of the local yarn stores carry it anymore, and while I can buy it online, I really prefer not to, if possible.
Instead, my darling husband found an alternative for me.
This is a nylon reflective sewing thread. This is something that can be used in sewing machines, if desired.
Here is how it looks with flash.
The beauty of this is that I can use it to make any yarn reflective. I tested it out by making a simple bracelet.
First, in normal light.
Now with flash.
I think that worked our rather well!
I look forward to using it with other types of yarn, or even with crochet thread. There's a lot on the cone, so this is something that will last for quite a few projects!
I'm quite pleased with it.
