DIY Starbucks Piggy Bank: Step-by-Step Craft Guide

Craft Your Own Starbucks Piggy Bank

Ever wanted a fun way to save coins? This DIY Starbucks piggy bank turns disposable cups into keepsakes. After analyzing this craft tutorial, I’ve refined the steps with material insights and troubleshooting tips. You’ll need basic supplies and about 4 hours including drying time.

Essential Materials

  • Starbucks plastic cup (any size)
  • Model Magic clay (Walmart’s foam-like air-dry variant)
  • Brown acrylic paint
  • White puffy paint
  • X-Acto knife
  • Elmer’s glue
  • Plastic straw

Pro Tip: Model Magic is ideal—it dries lightweight and spongy, preventing cracks. Avoid polymer clay which requires baking.

Step-by-Step Assembly

Preparing the Cup Base

  1. Trim the cup: Cut 3 inches off the top for a squat shape.
  2. Color clay: Knead brown paint into Model Magic until streak-free. Wear gloves to avoid stained hands—acrylic washes off skin but stains fabrics.
  3. Roll clay flat: Create a ¼-inch thick sheet large enough to wrap the cup.

Key Insight: Spritz clay with hairspray before wrapping. This creates tackiness for better adhesion without glue.

Wrapping and Shaping

  1. Apply clay: Place cup on clay sheet, roll gently with hands inside to prevent dents.
  2. Trim excess: Fold overhanging clay inward at top/bottom, then slice flush with an X-Acto knife.
  3. Smooth seams: Dampen fingers to blend edges—prevents cracking during drying.

Avoid This Mistake: Don’t over-handle clay after wrapping. Fingerprints become permanent once dry.

Decorating the Lid

  1. Create "drizzle": Pipe brown puffy paint in swirls on the lid. Apply two layers for 3D texture.
  2. Make whipped cream: Roll white Model Magic into a spiral. Glue to lid center with Elmer’s.
  3. Cut coin slot: Before clay dries, carve a quarter-sized slit in the lid using your X-Acto knife.

Time Saver: Work on the lid while the cup base dries. Both need 3+ hours to cure.

Final Assembly

  1. Seal the base: Insert the cut-off cup piece upside-down into the bottom opening.
  2. Add straw: Glue a 1-inch straw segment diagonally below the lid.
  3. Apply logo: Adhere a Starbucks emblem (from packaging or printed) with glue.

Pro Decorating Tips

  • Texture hack: Dab a sponge on wet clay for a ceramic-like finish.
  • Color variations: Use green paint for holiday editions or pink for Valentine’s themes.
  • Durability boost: Seal finished pieces with clear acrylic spray.
