Start by giving the laces a tug to tighten them a bit.
Now cross them.
Make a rabbit ear with the left hand lace.
Make another rabbit ear with the right hand lace.
Cross the left loop over the right,
wrap it over, and push the loop through the hole underneath.
Now gently tighten the laces.
Then give them a strong tug to fasten them.
Thank you, Miss Colleen.
