Hi Thierry
I used to have the exact same issues as you are experiencing, how I overcame this was to adjust the presser foot up slightly and lengthen the stitch length when sewing through thick material. Also once I have sewn the closing stitch I cut away any screm foam from the seam allowances and on some occasions I also trim down some of the layers of seams , more so if I have used piping I sometimes trim both the seams of the piping off about 2mm from the closing stitch . Just think ahead when you’re designing too it might just mean moving a join up or down a little so it doesn’t meet with another or multiple joins . I always try with scrap material first of the same thickness as there’s nothing worse than completing a project with some top stitching and your issue happens .
I hope this is of some help. Most of the tips I’ve picked up are from here and you tube there are some awesome craftsman on here with many many years experience
