Yay I love lissie so much. Good luck with the sewing. Have you signed up at pixiefaire.com . She does a free pattern each month and has sew alongside and video tutorials. I found a really cute and easy pattern free by searching American girl doll dress pattern free printable that you can make sleeveless, so it’s really easy. I’m not sure how to send the link but the pattern is all on one page. It has a front, back, sleeve and sleeve cuff (which I never use)

Congratulations!! I'd start on some simple shorts or tops for the modern doll first and work your way up to Felicity!! Sewing is fun!! Maybe you will soon be selling on Etsy and finding a way to pay for all your AG goodies!! Have fun!
