|I recently started using my mom's embroidery machine and here are a few things I've learned:
1) Line up your threads in order. That way you won't get confused as to which color you should be doing next.
2) Make thread sleeves or nets for each cone. Late one night, my son ripped the one thread net that the machine came with. I did NOT want to take a drive to the store, so I made a bunch using some slippery lycra fabric. I simply cut a strip the height of the thread cone and sewed it into little sleeves to slip on each cone. Make sure they don't fit tightly. It should be loose so as not to create any extra tension on the thread. Having sleeves for each one was a lot better than changing the net each time I switched cones.
3) Clip threads between each color change, otherwise you'll have a mess.
4) Have lots of bobbins prepared and prewound. Now I know why they sell prewound bobbins of white. I always thought it was rather silly, but now that I'm doing lots of machine embroidered items, I see the light.
I hope these tips will help you too. Have fun embroidering...
