Never Fear, There are "Loose Threads" on all Blast Zone Inflatables. In certain areas, where the person assembling the product reaches the end of an assembly seam, they will "Back-Stitch." this means they back track over the stitches they just made, to lock them in place, at which point the threads are tied off to complete the seam. The threads are cut, but excess thread may be left at times. If you consider this unsightly, you may trim the thread to an inch or so, however we do not recommend trimming threads shorter than that. The seam may look crooked in this area, but that is only due to the Back-Stitching during the hand assembly, and is no cause for concern. Leaving a little bit of thread past the "tie-off" helps ensure the seam does not unravel.
