Prior to lamination, from that pics it will be probably not easy ! The fabric just laying on the master.
In sequence : first layer 162g/m² glass - second the cotton of 112g/m² - 3rd and 4th 80g/m² glass.

The experiment of mixing the cotton cloth is interesting, no furter paints or decoration needed.

The hull appears to be very strong, suggesting lover glass sampling for reduction of hull weight.
The cotton weight was remeasured and found to be 120g/m² instead of 112g/m²

Someone suggested me that it is possible to use decoration drawings made on rice paper. Japanese tecnique
The paper under the resin will become transparent leaving only the draving apparent. This tecnique seems to be employed by Surf manufacturer for decoration.
Here a classical rice paper painted , just for a Good Easter to all suffering from earhquake in Aquila :
