Yea, I'm still very much the novice/hobby-ist and am in total awe of the work that is done with other tools that are other than manual ones such as your creaser, skivers, heck even a sewing machine! I am saving my pennies and adding my next 'toy' to my wish list which I think is going to be a skiver since I've ruined so many pieces with my 'hand skiver' or an air brush painter. I'm also pretty scared of buying really expensive leather right now until I feel comfortable with a process. I did bite the bullet to buy some really nice 'pull up' leather that I made a badge ID holder and have enough to make a couple minimalist card holders. I guess that's the best practice, - that is, practice on more inexpensive leather to get the steps and processes down so I won't get frustrated with more expensive leather. But one thing for sure, I learn something each time I finish a project and learn so much from people like you and others on this board!
Thanks!
