Here you will find step by step pictorial building instructions to my popular custom models. Some are free and some cost a small fee. However, all of them provide a parts list viewable through their respective Rebrickable pages. This should make it easier in gathering the parts and ordering what you may be missing via Bricklink wanted list generation and Bricklink store searching.
Use the top menu above to navigate to the various themes under Custom Building Instructions heading.
My custom instructions can be also found on my Rebrickable page
