Children's 10% Leotard Blocks

Children's 10% Leotard Blocks


This is the Children's 10% negative ease body and sleeve block (packaged together) for designing children's RTW swimwear and leotard patterns. This is without question our most popular selling item! It can also be partnered with the Children's 10% leggings patterns at the waist.

But we all know that children aren't very standard in size. My own 3yo is taller than my 7yo! Some kids are tall and skinny, some shorter, some bigger and some are close to adult sizing in their tweens. So this block set does something that no other block set does ... It comes in two different body lengths for the smaller sizes ... making it easier to select your size based on chest measurement then draft between the two options for body length. 

It contains 15 separate 2cm increment blocks from chest size 52cm to 80cm (and an extra 10 long body blocks for sizes 52cm to 70cm). It can be mix and matched for different chest, waist and hip sizes making it suitable for young boys and girls. There is added length in the sleeve already so you simply cut it back to the desired length. Very easy.
