"I'm very happy with the bag - it's beautiful and unique. I found it easy to sew but, as others have noted, the instructions were poorly written. I've been sewing for 55 years and was able to figure it out quite easily BUT I would not recommend buying this pattern unless you are very competent and confident in your sewing skills.
IF you want the video tutorial, buy the pattern and video together on the seller's website to save money. Frankly, since the instructions are so poorly written, video access should be included with every pattern sale.
All that being said, the backpack is amazing. It's really a beautiful bag."
