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.
I am an emroidery machine fanatic!!!! I download oodles and oodles of free designs from AllBrands web site every day. I cannot even begin to count the endless amounts of free fonts that they have. They have some really nice ones for monogramming. My favorite is the rounded. You put three letters with the two on the end being smaller than the one in the middle. If you have any trouble getting there just let me know and I will send you the attachment.
