Hi<br/><br/>Are these sentences natural?<br/><br/>1) Sometimes people <b><u>wrinkle their foreheads</u></b>, knowingly or unknowingly.<br/><br/>2) She ran her hand softly over his <u><b>wrinkled forehead</b></u> and <b><u>smoothed</u></b> it. <br/><br/>3) Stop <u><b>wrinkling your forehead.</b></u><br/><br/>Thanks,<br/><br/>Tom
