I am quite flattered by the response that my
carseat cooler received after someone pinned it to Pinterest.

My blog had more views in one day than in its lifetime! After many kind encouragements in the comment section, I thought. "Maybe I
will try and sell them." I had to make a new one for Claire since it vanished from the church freezer after VBS and Joy needed one as well. I made Claire's exactly the same as in my previous post, just a plain rectangle. But Joy's carseat was shaped differently at the top so I made her's in a different shape. After making these two, it became very clear that I will NOT be making these to sell. What a pain! A couple here and there is fine but I definitely don't have the time or patience to mass produce them. I decided to put together a tutorial for anyone who was interested in them.
This my first tutorial so....yeah. and I'm not a photographer.
First, you will need to look at your carseat, figure out how long and wide it needs to be. In my experience, the fabric should be 10.5 inches wide and 25.5 inches long. Once you have the right size and shape to fit our seat, cut 2 pieces of your decorative fabric, 1 piece of the thermal fabric. (I used an old felty blanket for Claire's and a bassinet mattress pad for Joy's. Any thick fabric that will keep the ice blocks insulted will do.) And 1 piece of knit fabric.
Next, sandwich the the thermal layer between the decorative pieces so the right sides off the decorative print are facing out.
Likes so.
Pin well and baste all 3 layers together around the outside edges.
Then, attach bias tape to one edge of the print cover and one edge of the knit. This will be the side that open up to slide in the ice blocks.
Then sew the two pieces together around the 3 sides that don't have bias tape to make a pocket
Next, you will need to get a ruler and measure out sections to hold the ice blocks. If you use the blocks that I recommend then each pocket needs to be exactly 4.25 inches. Any more and the blocks with slide out too easily, any less and you will never get the blocks in.
Make your line 4.25 inches away from your sewn edge. From that line measue .25 inch and make a buffer line.
Then use that line to measure your next 4.25 space. The quarter inch space allows the blocks to fit better and give the seat cooler an overall better appearance.
After you make 2 spaces on the bottom half or foot of the cooler, then , go to the top or head of the cooler to mark your other 3. The little space it creates is about 2 inches is right about where the cooler will bend to "sit" in the carseat.
You are almost done! Now just sew along your lines to create the pockets for the ice blocks.
Lastly, sew the bias tape all along the outside or the cooler to finish it off.
You are done! Insert your ice blocks!


(The plain rectangle version)
Roll it up and stick it in your freezer.
On days that we have a lot of errands to run, I put the coolers in an isulated igloo bag so they stay cool while we are driving. When we arrive at our destination, I throw them on the seats so the girls will be welcomed back to the car with cold, refreshing seats. My coolers stay cold for a good 6 hours, and that's in the Arizona heat!
Good luck!
