About a week or so ago, Fatima emails me and says get your hands on this month´s Evasões magazine check out the "manta" on pg. 29.
I bought it, saw it, and loved it. It looks portuguese to me. I called up the owner, Mr. Vasco Monteiro, of this particular rural house for rent called Monte do Adaíl and asked him. I found out it was made by his mother´s seamstress (from Alentejo) and if I call back in about a week or so he will give me her name.
