I'm new to this as well and have already begun stockpiling random jerseys to get done.
As you are new, take my recommendation, stop stockpiling and start getting them customized. I still have about 4-5 different jerseys I want to get done, but I always put them off because I would spend the money to customize on a SUPER GREAT DEAL GIMME type auctions and craigslist finds. Force yourself to never have more than 2 to get customized and go from there as opposed to accumulating projects. As of now, I currently have the following projects:
Keith Primeau - 2004 Black
Mark Howe w/ Lindbergh patch
Danny Briere 2010 SCF Edge 1.0
Theo Fluery Belfast Giants
Chris Pronger 2007 SCF Black Ducks
Rod Brind'Amour 2006 SCF White (Although I really want to find the red, but it's effin impossible to find 6100's it seems.)
Papelbon Cream jersey, was originally worn by a base coach so the 58 is already there, need to finish stripping it and get the name off.
Ninja Edit: Also have a Winter Classic jersey that I am still deciding on who to turn it into, will likely go Giroux.
See how that all adds up? It is frustrating.
