Hi Prezi, First of all try to make the dough soft. Keep the dough covered with wet kitchen towel, so that it doesn't dry out. If you want, you can rest the dough for 15 minutes. As soon as each paratha is done, keep it covered with a clean kitchen towel so that they remain soft. If you keep the parathas out, it tends to stiffen or harden.
