First of all, thanks Lavanya for this wonderful blog and letting me share posts..like you mentioned this is awesome for work from homers :)
I am starting my first one with a dress for my 16month old baby girl that I made with my husband's T-shirt. I've been interested in making a dress for her since long and I finally made one.. I started with just a plain simple yellow T-shirt. Once I finished stiching, I added the satin ribbon around the waist to cover my sewing imperfections and added the flower embellishments from one of her tops that was detachable. I am not exactly proud of this dress :) but I think it's a good start for more to come..Here's the link below where I found the instructions to sew..
P.S: If you're making a dress for a toddler who's 3yrs/older then I would stick to using your husband's or a bigger T-shirt. But for younger ones, I would use a women's Tshirt since I found my husband's to be too big for my lil one. when I finished I tried it on her and she looked like a Monk :) Hopefully she can wear it when she grows up!
