Where to get your wool:
I purchased mine from NaturesFabrics.com. It is the 95% merino wool/ 5% lycra blend interlock- WASHABLE. You can look to see if they have some available again (they have recently been out of it). As an FYI- make sure you get the really good stuff- there is a lot of inferior wool interlock out there for less, but you get what you pay for in the world of fabric and this wonderful wool blend is seriously like butter- just lovely!
How to prep your wool:
Wash and dry your wool twice to prep. You can expect to lose about 4-5" per yard when prepping- so order your material with that in mind!
How much material you will need:
You will need 32" of fabric to get two woolwraps- and taking into account shrinkage, a yard would be about perfect for two woolwraps. Since the material comes in a tube, cut open it is wide enough to lay out a woolwraps. This image shows what I mean- but it is just a rough drawing- it does not portray the dimensions accurately:
Here is another rough drawing to show you the dimensions (a picture is worth a thousand words)- again, it is not to scale but shows the shape:
