Theres a traveling sample pack around that you can loan and then ship to the next new member. Some samples are easily acquired, some are a harder to find. It would be a bit if a challenge to find multiple TRK and BCC samples, paulsons arent so bad as singles are around. Most china Clay's and ceramics can be purchased through the vendors here. Some also have paulsons samples but those tend to be a bit pricey.Pcf should sell a welcome kit made of chip samples and a guide with price ranges and info for new members. Might help along with a chippers journey.
