Maggiemaybe like you, I had handwriting lessons at school. We used Osmiroid fountain pens, filled from an ink pot fitted in the school desk. In those days my handwriting was excellent - and was remarked upon at my first job interview. What has happened since I do not know; like the OP, I can't seem to even write a birthday card without an awful illegible scrawl developing. I bought a fountain pen to attempt to improve the situation, but it hasn't worked. I blame lack of use, too, as emails are my method of communication now.
