Choosing the right size underwear or swimwear:

these products must be very close to the body (for stockings, panties or boxers in particular because these are small pieces for which the stature is less important than the corpulence and the age of the child....) it is recommended not to take an age higher than the real age of the child. For example, as long as a child has not reached 7 years old, make small pieces of swimsuits and underwear in 6 years. If in doubt, it is better to take the size below than the size above.

Material suggestions:

Underwear : jersey preferably in stretch cotton (with elastane) + ribbing to be cut into strips

Swimsuit : polyamide lycra (mesh swimsuit material) + swimsuit lining (claudia foam or same material as the polyamide-lycra swimsuit).

Stationery :

3 to 4cm wide elastic for the underpants
2cm wide elastic for swimsuit bottoms
Moss yarn and basic polyester yarn
Microtex needles (or at least jersey or stretch!), microtex is recommended for swimsuits
Twin needle for hemming or serger = cover serger
Plastic clips rather than pins for swimsuit material
