Congratulations on taking up modding! I suggest you update your profile to include your location so people near you can give you more specific advice.
1. I know it is difficult to search the forums when you don't really know what you are looking for. I did quite a few searches on TP forums and on Google looking for an online source of plastic sheeting in North America (with delivery to Canada). I searched for "plastic sheeting" "abs sheeting" "plastic" "polystyrene", etc. Within all the noise, I found some posts from quite a few years ago that mentioned particular suppliers in North America, but every one was outdated. A forum member was kind enough to sell me some leftover sheeting to get me started, but I had to look elsewhere for new stock. My source of good-quality black plastic sheets is empty industrial toner cartridges. All the plastic sheeting I will ever need (they are not recycled in my remote community). Perhaps you can look around for similar opportunities in your community.
2. Milliput and Apoxie Sculpt are both two-part sculptable epoxy products that can be sanded and drilled after they harden. I think people use whichever they can find easiest. The Milliput company sent me a list of Canadian sources upon request. I found Apoxie Sculpt at an online sculpture supply shop. I imagine it can be found in art and craft shops that sell sculpture supplies.
3. MilliPut and Apoxie Sculpt are sold in stores according to their respective websites. I would expect hobby shops to sell plastic sheeting, but I didn't find any at the online hobby shops I checked, but it could be that it is too bulky or not cost-effective to ship.
4. Quite a few shape mods have long extensions using plastic sheeting. Skarabajo used extensions in this mod
and ModernDayWarrior used plastic tubing that he made from plastic sheeting in this mod
5. YouTube is a good source of mod tutorials. I really don't think it matters if the shape mod in the tutorial is a 2x2, 3x3 or 4x4, you can use it on a 2x2. (I can't give specific links right now as this rooming house Internet I'm using is no match for YouTube, but PM me and I will send you my links on Friday when I get back home). The way I found the mods I wanted to make was to look in the Museum and then on YouTube for relevant tutorials. You'll only find tutorials for easier mods, but I think that is what you want.
I'm learning myself, and I don't have too many answers, but you are welcome to PM me. I am always willing to share what I know because I think sharing knowledge will strengthen our very small community. As I write this, there are 155 views of this post, so I think there is a lot of interest in this topic.
