Creative mending - embroidery thread and a thrift store find

I have my daughter hooked on searching out new (to her) and unique clothing at our local thrift stores.
She's been pretty fortunate so far and receives nice comments on the clothes she wears.

She picked out this grey wool blend cardigan.
We discovered the threads pull so easy and create holes in no time.
(not one of her best  finds and probably the reason it was donated in the first place)

I had to get creative.

She picked out two colours she liked and I went to work.

This was a challenge,  but a fun challenge.
(I won't dare show you the underside)

Bonus - she still wears the sweater!
