Frustrated and needing suggestions

Help, please.  I have several items pinned that I want to use.  I have them placed in the appropriate boards, etc. and have begun the process of moving them to our current curriculum board when it occurred to me that there will be several pins in one place. I have thought of making yet more boards to keep things organized (I like my duckies firmly lined up in a row), and to help keep things straight when I am having a rough time physically as there are still issues that haven’t completely cleared up yet.  However, I am afraid that even that will cause some problem as the amount of science pins alone could be quite overwhelming as I am working ever more dilligently to make it and others more of living subjects.  I have thought about making a master list, but truth be told, I am still adding to some of those boards and adding to the ones I will use, though, ideally that is what I’d prefer. 

While I used several last year and kept things fairly neat it really was no where near the amount I have pinned and plan to use this year, and I became a bit overwhelmed as we wrapped up our year. In th end, there were some pins that I really wanted to use that were left by the wayside. While it’s not the end of the world, by any means, I did spend the time looking for the pins, and really wanted to use them. There is a part of me that feels that I wasted the time spent looking for them since they weren’t used.  This is silly, I suppose, but true.

I received a tablet as a Mother’s Day/ Anniversary gift from my kids and husband, and have thought that perhaps there is a way to utilize that to help me keep things more organized.  However, I am still figuring things out, and haven’t quite determined if that is a dream or a reality.  At any rate, please share your tried and true ways for keeping your pins in order other than a board for current curriculum – or even ideas for how it might be done with a minimum of fuss and prep – so that they get used when you intend.

Edited to add that I have two girls who will be using different science, writing, and some history and math pins.  I also have one that will be adding to her photography elective with some additional pins, and one that will have both violin and piano related pins.  Those combined with artist, painting, composer, music, timelines, and Bible pins equals quite a bit, and much more than I used last year. Not sure if that is helpful in formulating ideas that would work, but thought I should include the variety just in case.
