Step 1: Supplies and Equipment
Thread - match your fabric, mine is ordinary white sewing thread.
Sewing basics - needles, scissors, etc.
Fray Check - use this when you intentionally or unintentionally cut a seam allowance smaller than you like. It will help stabilize the edge of the fabric so it doesn't fray out when you need it.
Iron and ironing board - iron on interfacing with this, and the more often you press things in place as you work them nicer your finished pieces will be.
You will need to choose to either use an iron-on interfacing OR use freezer paper and batting.
Fusible interfacing - 2-3 yards, relatively lightweight if this is for display, heavier weight if some dolls will be making regular use of it.
Freezer paper - you'll need several feet - cut the interfacing shapes on the pattern, iron it in place, and pull the paper before sewing things closed.
Batting - cut pieces to match the interfacing patterns, put the batting in before sewing things closed.
I used the interfacing for a smoother, simpler look (and the directions focus on this method), but feel free to switch it up and use the paper piecing and batting method for a softer, cuddlier tea set.
