I like your bags. And as far as the fabrics matching, well everyone has different tastes. It would be a boring world if everyone liked the same thing. As long as you like it, thats the important thing. LOL.
I too started off with the 4x4 machine. And was quickly addicted. Believe me when I say that you need the 5x7 ( at LEAST ) sewing field. But alas these machines are not cheap. I searched every where for the best deal and finally found this site. SewinSupplyWarehouse. I bought a floor model ULT2002Disney machine. This is in the pes format and that is the most universal format. I paid $2000. for this machine and was super glad to get this machine so cheap. Years later I bought another pes format for one of my daughters for $600. I know that this sounds expensive, but I bought the higher end machines with expandable capabilities. Im sure they have less expensive machines. As I say, I am an avid embroider. With my machine, I can do whole jacket backs. If you become addicted like me I will be glad to help you along with questions you may have.
