The Essential Step: Blocking 🫧
Blocking will set the shape of the yoke and make the large scallops of the hem lie flat and defined.
- Dampen: Gently soak the dress in water, squeeze out excess water (do not twist or wring!), and roll in a clean towel.
- Pin: Lay the damp dress flat on a blocking mat or towel. Pin the skirt hem, carefully defining each large scallop. Pin the yoke and straps flat and symmetrically.
- Dry: Allow the dress to air dry completely before unpinning.
Your beautiful Peppermint Stripe Baby Dress is ready to be worn! Enjoy the dramatic ruffle!
