Keep practicing, and write after some fonts that you think are beautiful.

I really glad to here that you would like to write my lauguage beaufitully. You can try to practice with thai writing practice sheets in this link below. All Thai people did it when they begin learning to write. Don't worry if your Thai handwriting is not beautiful. You can write it, it is already good for all. https://651379b9-a-62cb3a1a-s-sites.googlegroups.com/site/thairatppp/karban/baeb-fukhad-bi-ngan/แบบฝึกคัดลายมือ%20พยัญชนะภาษาไทย.pdf?attachauth=ANoY7coeZBG_0mf85_wsCz3XFqW4oDGOhiZnDeC3RktQOOVkcftQ8lgTFM0xlNZBYxhr-J06y-HGtlkJ_zBJxle5z4yk2jn4XpiEg7pjKJz2Un2_HgUPBccKaGiyBv_7AIZyXPb1CLD8gAoAvYlx7RoN_rTYZzJkvJdbHQK9vm1NYw9XbCj4YAhL7oTx0tPPtuRInArLki5dYjJ8Xj3eKg2JNxnbuwrC7w2ZRddXlcAIGEOl6OvzktgNEyPrBf__dwMmoFS5-TD9zosBuJhnGZDT9cjIP3p73sO1jeeQ92ahC48n2OS7cp8XZFZb7v8Nc_RP5ShWpXCaqamBlv_OcAMHTH_6SrItmJvcvhz6ErFe79zqc5ZDNvIDljIWJhPD1kmv9r1qG3ujIebeXmgRs8lVcX-YST2PXg4MnpDCURpT8GZb18veyoCamRq1BUNczH8M7l9FXnNm86m6F4GnrXV66_O2NfK-t-EUaUpcQLWTFAoH3vvQFkvhz6Xdnnb2Yw_dm8QSkETSDr27jwQoXydGpVXmKMtLcgWmkKbA2ft02I1vo2n1s8sUe7cTEjsR-I7nydGTm_vHyt25WXyr2S6IkTOIhTFXUQ%3D%3D&attredirects=1&d=1

well, you had better to practice with dotted fonts! :) you can download it free, just google it. I think it's the good way to practice it and like the other said... Keep practicing!

Keep writing in Thai and you'll see your best Thai handwriting which suits to u most :)

Better you write it more and more
