Reinforce woven fabric where it is thinning or weak - PEP BB textile.straw.ireinforce

This is a badge bit (BB) that is part of the PEP curriculum.  Completing this BB is part of getting the straw badge in textiles.

In this project, you reinforce woven fabric so that it is invisible.

In this badge, you are demonstrating that you understand the structure of woven cloth, the skill to match the color, materials, and texture to the original fabric, and to reinforce the woven structure to create a truly invisible mend.

To complete this BB, the minimum requirements are:
- material must be a woven fabric
- reinforce thinning or damaged fabric, not a seam
- must be a truly invisible mend - not obviously visible from 3 feet away
- thread/yarn chosen matches fabric in color, texture, and size

To show you've completed this Badge Bit, provide proof of the following as pics or video (less than two minutes):
- the thinning or weak fabric
- the material(s) and tool(s) used
- repair in process
- the same piece after mending

Clarification: repairing a seam does not qualify
