If you were going to sew some thermal underwear but forgot that winter was coming, this is your wake-up call from me ;) Made with #Polartec #Powerstretch, sadly not sponsored but I just love it, for my 8y old. A *collar-blocking* is unintended and was made to fix a measuring mistake, but hey, now it has an extra "this is the back" marker ;) #sewing #thermalUnderwear
