Well I went through the book "Creative GEWE Wet Flies" in detail yesterday, and WOW what fun.
Wonderful learning experience as well ...for the look at materials I'm unfamiliar with, Geert's tying techniques, his many creative and effective patterns, and just getting to know the man better...and what a truly wonderful person he is...but I already knew that from personal contact. Same goes for his good friend Dale.
The book is extremely well done. Full color on every page, words from both of our friends Dale and Geert, as well as a world of information. Anyone who is part of this forum knows them both...and based on that alone I'd tell you all to get a copy of the book. Time and money well spent.
PS - I learned the proper way to pronounce Geert's name too...but you'll have to buy the book for yourself to find out for yourself
