I paid £300 plus pounds to do a 3 day class at the NEC Birmingham UK.with a named quilter. The sewing machine was provided plus irons and boards. We had to provide all our own fabric. Enjoyed the company but would not pay that high a price again. Done it once and found out it is not worth the cost.
Are you going to go for the experience then if you can afford go for it but if you have to be careful with money etc think very hard as to what you want in the end.
