All of our products are 100% wool, 100% natural color and all of our wool products are 100% guaranteed. If for any reason you are not satisfied, return whatever you did not use and we will refund your money on the unused portion: you just have to pay the shipping costs both ways. This does not happen very often but we don't want folks to feel they are "stuck" with a fleece that isn't right for their particular project, once it arrives and they can see it. Our fleeces have earned the Vermont Seal of Quality.
