The cupcake pattern is all over the internet, but I thought this one was the cutest.
The carseat blanket is my own design. That was done with Red Heart Supersaver Mexicana yarn. It's rainbow colored. I know, Red Heart yarn is c**& but I love the colors. I figure it will soften if my daughter washes it in Dreft.
Most carseat blankets are 20 by 24. I made this one larger thinking it would last a while for a toddler. My size came out to 21 by 26. It was done in a twin rib pattern so it's the same on both sides, reversible.
Cast on a multiple of 3. I used size 10 needles and cast on 90. First row: k3,p3 across. Second row: K1,p1 across. You just repeat these two rows for the pattern. About halfway up (12 1/2 inches), I knit 41 in pattern, bound off 8 sts, knit 41 in pattern Wrong side, knit 41 in pattern, cast on 8 sts, knit 41 in pattern. I knit straight in pattern for one inch, then made another slot in the same manner. I continued straight in pattern for the last 12 1/2 inches.
My way of thinking is that you'd need a double slot to thread the crotch strap of the carseat through. This can also be used in a stroller as it's small and won't drag on the ground. You won't lose it. I couldn't find any patterns for carseat blankets with a workable slot on the internet so I made one up. Feel free to use this as you wish. Makes a great baby gift. This pattern would also be good for knitting scarves for gifts, especially for men.
