Amazing Brushstrokes

Review of Amazing Brushstrokes by Kannikar Sukseree

This is a beautifully presented book with many pages of explanations of techniques and step by step photography taking you through each project. I think there is plenty of work suitable for beginners and more experienced crafters. The designs are exquisite. The grids and tools used are Pergamano as you would expect from a Pergamano book! However if you try to use a PCA grid you will not get the same look as the illustrations.
