Building in Second Life

I found Building in Second Life to be frustrating. You have a very limited amount of objects to choose from and build upon to create even bigger and more elaborate objects. I watched several tutorials on YouTube as well as read about building processes. I learned how to put objects, Prims, together and I came out with a trestle table and chairs. I did not want to change the texture or color since this was supposed to be a wooden table.
I started with the table, learned how to create the top out of a cube by stretching, resizing, and rotating. After the top I started on the trestle by putting 2 semicircles together with a flattened rectangle in between. I linked all of these Prims together and copied it. I then I had to figure out how to rotate, reshape, and place the legs under my table top. It took quite a bit of time to adjust everything from different angles so all of my Prims would fit together as a table. I then linked all of these as well.
The chairs were even more tricky because it required working with about 8 different Prims. I constructed all of my pieces and put them together using the same process I had figured out for the table. After much trial, error, reshaping, and linking I had a table and chairs. It is now available in my inventory. I had hoped to save each individual piece in my inventory, and thought I had, but when I was finished I realized the individual pieces did not save. I think I should have right clicked on each Prim I had created and selected "take" in order to place the Prims in my inventory. It would also probably be easier to create Prims if you were using a mouse, but I wasn't at home and did not have one on me.
