I have downloaded some paper templates from Pixel Scrapper which were made in Photoshop. I don't have Photoshop but have been able to open the files in GIMP. One of the templates I downloaded was a plaid one and I have tried to colour the lines etc. using GIMP, but I can't seem to access the layers of the template to be able to colour each layer with a different colour, it's as if the template is all on one layer so I cannot colour say a whole line in one colour, it will only colour each part of the line until it connects to another line crossing it, which looks very messy and there are bits that I just cannot access to add colour to it.
Does anyone know if there is a way to colour and use PS paper templates in GIMP
