I thought I'd talk a bit about my working process on a block (at the risk of boring a large percentage of my readership). I'm not particularly organized when I work as you can see by the evolution of my blocks. I know a great many people work all their seams, then all their centres, and then add the beads, buttons, etc. I don't. I get bored and jump all over the place working on whatever pleases me at the time. I add the beads and such as I go along, even tho' there's a certain amount of angst when the threads get tangled around them.
I don't hoop my work and find that works best for me. Some people can't work without one, but it just gets in my way. I tend to use a lot of tissue paper for patterns (I make an outline of the area I'm wanting to fill and then sketch out a pattern, pin it on, and sew through the tissue). A pair of curved tweezers work nicely to remove the paper when I'm done. I also use waste canvas in some areas and when I want to be sure a seam is even I will use a piece of 1/4" masking tape as a guide. I just make sure I remove the tape as soon as possible, or it can leave a sticky residue behind. Sometimes I don't use any of my props and just simply wing it. I also use a layer of heavy interfacing behind any areas that have a lot of weight (ie. the button clusters) for additional stability.
Hope you enjoyed reading about my working process!
