Hi Prestigeartsy and welcome to this forum.
Creating script fonts is a great subject and a lot of fun. It is also a very broad topic, so it is difficult to give precise advice.
I take the following approach:
- On a white sheet of paper, I have faintly drawn guide lines for the baseline, ascender and descender.
- then I write or draw my letters with sufficient spacing using a black caligraphic pen.
I scan the paper, which is better than taking photos with my mobile phone.
- in Photoshop I optimise the scan so that the guide lines are no longer visible.
- in Illustrator I vectorise the image. Combine one letter at a time into a group and name the group “A”, “B” and so on in the “Layers” palette.
With the necessary guides like “baseline” I then draw my letters in Fontself Maker.
- adjust the spacing etc.
- save as .AI file and as font .otf from Fontself.
(I will write an article about it in the next days.)
If you have an iPadPro and a pen or Wacom tablet, you can also draw each letter digitally. You have to try out how and where your letters look better.
