So far the testing I have done, not really sure whether it is due to faulty UV resin, but it seemed to be harder to dry for thick layer, even after put under UV light for 15 minutes. Resin layer is just 3~4mm.
Had been buying resin supplies since and tested the difference of UV resin and epoxy resin. I have bad experience with UV resin on the second batch, suspecting mainly due to old stock.
Was planning to re-do the accessories card for the leather cover planner. Last time did a eyelet closure, this round figure to use a simple fold tuck in.
