I am going to resist the opportunity for puns…
While many appreciate the realistic details of Iplehouse male private parts I would prefer them to be less prominent.
They tend to cause unattractive wonky bulges in pants, that’s why I use to pad their crown jewels. Somehow it’s even more annoying with the FID guys, maybe because they are the better posers and the issue is more visible with posing.
The easiest way to pad them would be a piece of felt or other soft material and some tape. It works fine if you just want the doll in a stand to look nice, but if you want to pose the doll the thin strip of tape between the legs comes off rather quickly. After a padded thong proved to be impractical (it slides off to the sides) my guys wear trunks now.
They are very easy to make and keep the pad in place. And depending on the fabric you pick they work as swim-trunks as well.
Place the pattern in Word or something similar and scale proportionally to 15cm width. Only add seam allowance at the waist and legs, following the dotted lines. The dotted line for the pad is just a placement help.
For all other seams there’s about 4-5mm seam allowance included.
