Although I strive to provide affordable work I totally understand having a tight budget. So for reference here are a few personal recommendations.
Google fonts: Meddon (handwriting) for a “modern calligraphy”, Felipa (handwriting) is exactly the same as my Italic sample
Certificate font (free download)
Manuscript font (free download)
Paper is also important. Find something like this mixed media purpose and you can’t go wrong! Parchment is fine starting at 24 lb weight!
If you’re new to calligraphy I also recommend practice paper. You’ll get a small amount included with the pen kits.
