I do not get any kind of financial reward for suggesting any particular vendor of yoga supplies, you can easily get most of these from your local Target or Walmart, and you can find them online. I only offer these as a possible source. If you have questions, let me know, and I also bring some supplies to classes for students to borrow, so you can try things out, and decide what is best for you.
Beautiful rubber mats, but pricey: https://www.sugarmat.com/collections/new-arrivals/products/chinoiserie-time-again-vol-i-pu-yoga-mat-5mmMATS
Yoga Outlet has great prices, and mats of all thicknesses and sizes. 5-6MM is a comfortable mat to cushion joints. This mat is longer, and cushier than a standard class mat.
I would recommend getting cork blocks from Walmart. Cork is sustainable, and you are avoiding PVC. They have mats and other supplies too.
A sturdy woven blanket is the best for folding and rolling in a class, and the heaviness is calming for most people.
This blanket from Yoga Direct is the best price, not sure about the quality.
Also, you might consider….
This can be a great help to your meditation practice, and for restorative yoga poses. These are cotton, have easily machine washable covers, and sturdy.
Straps, towels, etc.
As you practice, you may choose to add other supplies. Chat with me if you have any questions!
