  • 3. Cut out numbers following lines traced onto paper side of fusible web.
  • 4. Following fusible web instruction, adhere appliqué numbers to remaining fabric squares in pairs. If you placed a yellow number on a green floral background square, use a green floral number on a yellow background.
  • 5. Using appliqué, carefully stitch along inside edge of each number using straight stitch.
  • 6. Piece squares together, making sure they are in proper order.
  • 7. Layer quilt sandwich. Using fusible fleece, fuse to quilt top and then use basting spray to adhere quilt back.
  • 8. Using an erasable/water soluble pen or pencil, mark lines vertically and horizontally across entire quilt. Start 3" in from left and go across and start 3" from the top and work your way down. The intersections will be where you center quilt in embroidery hoop for quilting.
