This is a lovely site and to be very shallow about it the women and girls are really beautifully dressed - a real example to other Catholic women. 

The woman who runs this blog also has an Etsy shop where one can find nice items such as this little book of Catholic Chats for Children:

Every "chat" is 1 - 2 pages only, which works great for busy moms and little children. Nice daily addition to your home - school.

Sorry but $68.00 for an apron is laughable.

Also an apron is meant to catch the dirt,spills, etc from getting on your clothes NOT a place for an image that should be held in reverence.
There's a time an place for everything and I find images on clothing distasteful

And what to say about her lovely aprons?

Would not these aprons be worn in May crowning processions, especially those in Spain or Poland?

In Europe, aprons are part of the national dress.

The lady has great skill with needle and thread and design.
These aprons have no resemblance to a Polish costume and this isn't Europe.
Why would you wear something that draws attention to the bust line?

Below are traditional European costumes

I certainly would not wear these aprons in a procession.

However, young flat chested girls might  and with veils covering their heads, and with long ankle length modest dresses or skirts with long sleeved blouses, they would look very modest.  I do not think that these aprons would be appropriate for any other purpose. In other words, if worn in a procession, they should be immediately removed and carefully put away after the procession.

These aprons would be most appropriately worn in Mexico where they honor Our Lady of Guadalupe.
