Dacron Option: The use of Dacron will make the finished product look more filling, smoother, nicer and feels a lot better. Dacron can also be used to cover up defects on the foams. However the addition of Dacron will push up the price considerably due to the cost of labour (generally it uses spray adhesive to glue them together, however this is not the only method). In fact Dacron itself is not expensive, the retail price of 2.4m wide Dacron is around $10/m. Hence purchasing Dacron separately and do it yourself can be another economical method.
