Since the summer has begun (sort of) poor old Bea has been suffering with getting very sweaty in her car seat. Luckily I have found a solution.
I used an old baby towel (the square ones with the hood) to make a car seat liner. I just took some measurements from the seat, cut out the shape and bound the raw edges.
She certainly seems more comfortable and I can just whip it out and wash it when needed. Has to be the most practical thing I have sewn yet!
