As promised, I have put together a tutorial for this notebook-pouch. It fits my daughter's computer, which measures 12" X 8", but you could easily modify the cutting instructions to fit a larger laptop, or smaller tablet.
You can find the downloadable PDF instruction on Amy's blog, During Quiet Time. Amy is not only a paper-piecing super-star, but she is also the one behind the Little House on the Prairie Quilt-Along. This girl is talented!
If you have questions about the tutorial, you can email me at freshsqueezedfabrics (at) gmail (dot) com.
Have a lovely day!
