100% CottonWash separately before use. Optimal absorbency comes after 3-6 wash-dry cycles. Warm Machine wash. Don't Bleach. Avoid Fabric Softeners. Cold/Warm Tumble dry.
Cotton yarn goes through a fair amount of work before it reach our towels. To truly activate the cotton absorbency, it needs to be soaked (or washed) around 5 times before it's reached its maximum absorbency. It'll still dry you out of the pack...but proper comfort comes down the track. Wear it in!
Fabric softeners might make your towel feel soft but it actually inhibits the drying capability of our yarn. Think of it like coating the yarn with a waxy kind of layer...it might make it feel nice, but it'll be smearing water instead of soaking it up.
Once our towels are fresh off the loom - they're folded, ironed flat and then hand stitched to seal the edge. Naturally there's going to be the odd horizontal yarn that comes away. Don't stress that your towel's going to unravel..it's simply a few lose strands that'll come away for the first few uses.
Just common sense this one.
We're all for basking on a warm rock, but if it's one of the jaggard, really rough kind of rocks....find a smoother one. If the yarn catches on something sharp or abrasive it can potentially pull. If this does happen - snip off the dangly bits with some sharp scissors and happy days.
Washing is generally pretty harsh process. Excess energy || Excess water || Excess effort.
Like any fabric, over washing it won't exactly ruin it, but it'll effect it somewhat. There'll be shrinkage (5% max), slight colour fade and general wear and tear.
Just try to do it less. Towelling off outdoors won't get it all that grubby. But if it happens to follow you to the next overnight festival...then definitely wash it.
A little tip - roll your towel up and stick it in the freezer over night if it's starting to pong. This kills the bacteria. You'll have a fresh (cold) towel, without the pong and you didn't even need to wash/hang/dry - win-win.
If you're near freshwater, dunk the towel a few times, ring it out and hang it close by to dry. This is by far the best way to maintain a healthy cotton yarn.
