Pat Combee
Awesome pattern

The pattern for the backpack was received on a continuous sheet of heavy stock paper with the entire set of pieces nicely printed. It was very long and wide with minimal folds, & was received in a heavy-duty zipper bag. It was fun to lay out and cut out my pieces & it gave me the idea of how this pack would go together. I am very satisfied with the pattern, and it saved me a lot of time and money going to a print place to have it printed in full size. I live in a rural area and hate to drive to larger cities. Thank you RSBTR for offering the full-size pattern.

Hi Pat, We're happy to help! Thanks for the review .

Looks Great - Excited to build my skills to actually sew this project!

with the opportunity to buy both the pattern and the cutouts at once, i jumped before i feel comfortable with this kind of project, but will be up to the task soon and this removes one hudle--quality printed out patterns!

Did not use

I purchased this to get an idea of what a backpack pattern looked like, but ultimately decided to go with a different design.
