Upscaled 3-pocket bag

I recently made a bag I loved -- the 3-pocket bag from a pattern by NapkittenPattern.  It turned out smaller than I thought, so I decided to try upscaling the PDF file.  After several tries at different percentages, I printed out and used the pieces at 170%.  There are several issues that come up when changing the scale of something.  I had to calculate by hand some pieces that were dimensions only, such as the bottom piece.  I also had to change the handle design, because the smaller version didn't work at the larger size.

This picture shows the difference in the size of the pattern pieces:

Here's my final version.  The bag is large enough to be a weekender tote.  I Love It!

The difference in size:

The inside still has a huge zippered pocket and 2 large side pockets.

I covered the bottom piece with iron-on vinyl (my new favorite product).  The sewing of this larger bag was actually easier than the smaller one, especially the bias binding around the side pockets.  I like the handles on the smaller bag more, but I found some cool black buttons to accent the larger bag's handles.

This project definitely took more work, starting with having to piece the patterns together with tape, and adjust other measurements, but it was definitely "do-able" for an advanced sewist.

Do you have a favorite pattern that you would like larger or smaller?  Give this method a try.  You might surprise yourself.

Happy Sewing!
