I see there are several posts on the tear ducts and have tried the recommendation, but still struggle with them opening. I make sure they are super thinned using a dermel with a sanding drum, focusing on about a 3" circle around the duct to eliminate shrinkage and pulling. As for the form prep, I use a scalpel blade to start the initial slot, which is not straight in, but up at an angle. I circle the duct opening with critter clay and using the lip tucking tool, push the duct into position and close the critter clay over the duct opening. I ensure there is adequate hide paste. The head is bagged for several days, checking often to fix any movement. I have tried to use Pins to hold in place but do not get consistent results. Looking for some ideas/methods to try on the duct. any thought or input will be greatly appreciated.
