What should be avoided when repairing a stretch-in cut-pile carpet using an insert?

When repairing a stretch-in cut-pile carpet using an insert, avoiding trapping yarns is crucial for several reasons related to the integrity and appearance of the carpet. Trapping yarns during the insertion process can lead to distortion in the texture and may create visible bumps or irregularities in the carpet. This disruption not only compromises the aesthetic quality of the repair but can also lead to premature wear and damage in the repaired area.

A successful repair requires that the new insert is seamlessly integrated into the existing carpet. If yarns are trapped, they may not lay flat, which can result in an uneven surface that detracts from the overall look of the flooring. Additionally, trapped yarns can make the area more susceptible to snagging or pulling, thus shortening the lifespan of both the insert and the surrounding carpet.

The other considerations, such as using excessive adhesive or cutting yarns unevenly, indeed affect the quality of the repair, but they do not have the same immediate visual impact or structural implication that trapping yarns does. Applying seam sealer prematurely is also a concern, as it can hinder the proper adhesion and positioning of the insert, but does not directly alter the structural layout of the yarns themselves in the same manner trapping them does. Therefore, ensuring
