As a teenager, a friend and I had a doll clothes business.
We made a bunch of doll clothes and went door to door to
sell them.
I don't think we sold many because we did not try to sell to kids instead trying to sell to their moms who answered the door.
I don't remember using patterns.
The pattern companies sell doll clothes patterns or there are some on the internet.
I looked on Pinterest where I did see some patterns. Etsy might have some.
I found this on eBay:

Angela's doll clothes are beautiful. What a lovely memory.
Nikki, if you make some doll clothes I hope will share them here on the forum.
I like your idea for using velcro.
