Yarn Needed

I am working on a blanket and am currently using Bernat Premium 100% acrylic 198g/7oz, worsted Black and Red. I am looking for a yarn of the same weight and feel in a Gold/Yellow solid color and I am not sure what to us?

Welcome to the forum!
Yarnsub.com is a good source for just that, yarn substitutions. Here’s the link for the Bernat Premium and suggested substitutes:
