Create simple repeating tiling polka dot pattern for Spoonflower fabric

Hi! I need a high resolution or vector file that will tile for Spoonflower fabric. It will be light yellow with 2.5"-3" darker yellow polka dots. I also need a striped pattern, with the same colors, again for Spoonflower fabric. Pretty easy stuff I just don't have time to do right now. The picture shows the fabric I need, but I need human sized proportions instead of the doll. Thanks for your consideration!
