It sad to think that your would ever regard yourself as a bad or lesser quilter. You are fabulous!!
Each of us brings such diversity to the art/craft that results in a equally diverse finished project. This is the fasination!
I have a a few machines .. my favorite is a circa 1950 knee control singer.... nothing fancy just a great machine.. 95 % of the sewing I do is on that machine. ..Once I was in a quilt shop that sold very high end machines. as they cut my fabric .. the person cutting asked me "what kind of machine do you have?" because I did not have the brand they sold it was apparent they thought I was a lesser quilter... Well I was so affended I could not keep myself from responding " I learned a long time ago .. its not the machine that makes the quilt ... its the person operating the machine". .. "and in fact no machine is really neccessary". My point is that each of us uses what we have, to create works that are first pleasing to the creator of the piece. If you are happy thats the only measurement that matters.
