How do you create this contrast between fluffy yarn and normal yarn in your rugs?
Hi everyone. I have a tufting kit coming next week, along with a cozytuft frame. I am excited to begin this journey and have been consuming so much tufting content. One thing I can not figure out for the life of me is how people are able to make designs that have very fluffy parts and normal short parts. Are they using 2 different types of yarns for this effect? In the 2 photos I'm showing as examples are what I mean. I know this is probably not a beginner thing to try and I don't plan to try and create anything like these at first but it is making my head spin trying to figure out how you accomplish this effect because I have so many ideas in my head that this would be perfect for.
I think it's called shaggy rugs? I hope I'm conveying this correctly
