Not sure which I love more: traveling or shopping!
I usually take a huge old Scout bag folded flat inside my suitcase to schlep my finds home, but sometimes you just want to travel light! Pillow covers or textiles are a great, lightweight souvenir.
They satisfy my need to seek out something with a local flavor and are a daily reminder of that street vendor, souk or craft market once I’m back home.
Don’t limit yourself to actual pillow covers. One of my favorites started life as a hand towel, another as a rug fragment.
One was maybe 6 USD in a Cambodian airport shop. A beautiful but dirty and torn scrap of patched saris was a lucky side-of-the-road find in rural India:
Now, with a down insert and trimmed with mirrored key fobs, it proudly sits beside a store-bought Christian Lecroix embellished pillow that cost about 20 times as much! Almost anything can be made into a pillow. Be open to the possibilities!
