Laminating is where you layer multiple parts together to make it thicker. You don't have to redo it just glue another frame over the one you have one there. You could do some searching around the links area of the forum. There should be some websites that has some basics on card modeling. When I first started this hobby I was doing worse then you but practice makes perfect.
What we obtain too cheap, we esteem too lightly: it is dearness only that gives every thing its value. Thomas Paine, Founding Father
