>>532496>glue stickFound the problem, glue stick are useful for certain necessities but nor for paper crafts, use white glue or similar.
To fix your problem you can try to apply a small amount of white glue or liquid glue using a glue syringe like pic related.
You can buy regular syringes for cheap in any drugstore just $0.50 for a 10-20ml syringe, just be careful with the needles, or you can buy glue syringes in hobby-stores, they are more expensive, the only difference is the blunt-end needles.
