We developed some Acrylic templates, by using it, you no need to draw lines on the leather, just use knife to cut leather directly, save you some time.
But we should admit that acrylic pattern is not as detailed as downloadable pattern, downloadable pattern has more hits on it.
We use 2.0mm acrylic board, after lots of test, 2.0mm is the best thickness.
