if the template is marked heatproof, then i would guess that it is provided to iron your fabric over. the rounded end of the template should make sure that your rounded ends are all the same. didn't instructions come with it? pointed dresdens are much easier, but my opinion is that the rounded ones make a prettier quilt. as the others have mentioned, this is a challenging quilt for your first attempt. don't be afraid to keep asking questions if you have doubts about the next steps...
