Think about how you like have your tools available to use. I have a similar bag that was intended for serger feet and tools. Honestly, I don't like looking through each page to find the item I want to use. Is it on page 1 or back on another page?
A double layer tackle box works better for me. Lots of storage, one lid to open, and all is right at the fingertips. The box holds everything I need and more; scissors, needles, bobbins, etc.
Good luck finding the perfect solution.
