• Do not lay your paper or fabric entirely on the glued surface; Put it down little by little, smoothing it over with your fingers to expel the air. ​

​

• To prevent bubbles from appearing when you want to glue paper, one technique is to soak it on the reverse side with a foam roller or sponge. Wait a few minutes then stick it on your cardboard. Indeed, the wet paper will stretch, and by drying, it will regain its initial shape. Regarding artisanal papers, there is no need to use this technique, however, do not hesitate to do it with mechanical papers.

​    

      It is possible that by drying your box, it curls up too much. There, the solution is simple: put in press.

   

      And if despite your efforts, there are still bubbles after drying, put a baking paper on your structure and iron it.            Under the effect of heat, the glue will "reactivate".

​​

• Some fabrics are difficult to stick and others are warped. Try this technique: Take paper, such as a printer, coat it regularly and generously with glue and let dry. Then place the sheet on the glue side on the back of the fabric and iron with steam (if your fabric supports it).

​

• A glue stain? Place a baking paper on your structure and pass the iron without steam.
