@letscreate sometimes is really easy to create them, and sometimes gets really difficult 🙁 I recommend you when trying to create a pattern (A NORMAL ONE) to begin with less threads, between 6 and 8 threads, also use really different colors, complete out of contrast to avoid confusions and you can always change them before submitting the pattern to be controlled and accepted and the very very best is to make the first pattern with two or three colors.
For Alphas is another story. You can make them from a picture, the best ones are black and white pictures and you can add the colors later, using the letters from the alphabet and giving a color to the letter.
I hope you understand a little my explanation ❤️ , want my English is really poor...I'm not using the Google translator or any translator anymore, Sorry 🙁
