Making a butter squishy yourself is a rewarding craft project that combines creativity with tactile fun. From my experience, one key step is to carefully choose the right materials: washable markers like the ones mentioned in the instructions are perfect for adding vibrant colors without making a mess. When drawing your design before cutting, take your time to create smooth outlines that suit your preferred shape. Using tape helps hold pieces securely while stuffing the squishy, so opting for a strong but flexible tape is essential. Stuffing the squishy evenly makes a big difference in the final texture and squeezability; I found that using lightweight stuffing avoids making the squishy too heavy or firm. After assembling, gently press your squishy repeatedly to settle the stuffing and ensure the shape holds well. Personalizing with colors and shapes not only enhances the squishy's appearance but also makes it a unique stress reliever or desk toy. This project is enjoyable for all ages and a great way to upcycle small craft supplies at home.
