I designed these booties back in 2011, and they are still my very favorite pattern <3 I have made several pair, in all different colors and types of worsted weight yarn, but my favorites are using the Bernat Mosaic yarn.
Pattern can be found here~ http://www.triflesntreasures.com/store/p169/Crocodile_Stitch_Booties.html because I always get flooded with requests!
