Has anyone had good experience with Kucharik? I emailed asking for measurement's of knee warmers and he was very curt and did not really answer the question. Then I replied asking about what a "seat liner" looked like, because I could not find it on their site. Again, he did not answer the question, but replied with it is made of wool. ********** I will order the knee warmers to start, because they have a no questions asked return policy, but the replies/customer service doesn't seem very good. Maybe he was having a bad day?
