I saw this rhyme and have saved it to use for my son in a few years. I hope it helps you:
Two little bunnies want to tie their shoes. (make loops with each end of the lace)
Need each other to know what to do. (hold them to make them the same size)
Right over left, left over right (show how to tie a knot using the loops)
Tuck their ears and pull real tight. (pull the loops)
