is there I can find different patterns for thread art and weaves..

Lots of places. Clemens did a book on that very thing, so did Billy Vivona. Visual Wrap and Visual Weave has a library of thread patterns for both.

I've found Billy's book to be very helpful

Once you learn some of the basic patterns and the principles of the different wraps, don't just copy them. Experiment and try to develop some of your own variations. You will find it fun and challenging.

One of the best ways to quickly shorten the learning curve is to combine the pattern books already mentioned above with software like Visual Wrap.

By sitting down and working through some patterns in the books with the software, and then use the software to display the image as you progress through the pattern steps, you will have a highly visual teaching tool to help you understand the effect of each step in the wrap.

once completed, you can experiment by taking individual steps and modifying them and again instantly see the results of the modifications without ever having to lay down a thread. You can reposition individual steps up and down in the execution order as well as seeing what happens if you change a one for one to a +1/-1 etc. There are lots of creative options.

Once you build a strong understanding of dec wraps in this manner, you can further extend your depth of understanding by reverse engineering the layout, spacing, and sequence of steps from someone else's finished patterns in the software. When you can do this, you'll have a very solid foundation to do the creative kind of work Randolph encourages us to do in his above post.

I've seen people do what I just described and in a month or two gained as much knowledge as us old timers learned through years and years of trial and error practice... welcome to the information age...
