I have been seeing a lot of these color-block infinity scarfs around. So, the last time I was in the fabric story, I checked out the knit material and they had stripes!!! I got some navy striped and plain navy to make my scarf (1 yard of each).
Folding the material in half, I cut it 21 inches (or 42 inches total unfolded).
Then I cut the lenght 38 inches. Make sure you cut the striped material the direction you want the stripes to go. I wanted mine horizontal.
Next folded the long piece in half and sewed down the long side.
Then I turned the long 'tunnel' of material right side out. I folded the navy end in a little and then just slid the striped piece in and pinned.
And here is the finished scarf!!
