I have tons of old singer attachments and have yet to use any of them. They are so different from the newer machine but oh did they make beautiful quilts with those attachments. I have the manuals for them but have not done anything with them other than be so proud to have them. I am a collector but tend to be so busy with all the quilts I make on my 7570 and Juki that I just haven't taken the time to learn them other than the straight stitch foot.
