I love these!!! You make me want to get an embroidery machine so I can make these also.
You can get an embroidery only machine for a little as about $300.00. Brother makes the PE 500. It will be limited to only 4 x 4, but I will tell you that even though I have a machine that is capable of 5 x 7, none of the designs on these towels are larger than 4 x 4.
You can do a lot of embellishing with even a small area machine for not a lot of money.
