Nova Scotia's children's hospital is running low on crucial supplies — of finger puppets.

For decades, the IWK has been using the pint-sized puppets as small sources of comfort for children undergoing blood work or other medical procedures.

The hospital says it gives away more than 1,000 puppets a month to patients and their families, each of which are hand-knitted by volunteer groups and individuals.

But the hospital's puppet coffers are currently running low and on Tuesday, the Volunteer Resources team put out a call for stitchers with a little extra time and wool to help them restock.

"The finger puppets are very much appreciated and we've been told that many patients keep them well into adulthood," said the IWK in a Facebook post.
