Almost invisible! I used this technique while making coasters out of scrap material that I have from other projects.
Iused mostly material that I have purchased at The Quilt Store and Austin Craft-O-Rama, smaller scraps that I have saved from other crafts. I embroidered hummingbirds from Jenny Harts book Craft Pad on recylced linen I found at the Blue Hanger, a treasure trove of fabric for any crafter in Austin.
Many birdies and many bright, cheery fabrics, good stuff!
Jenny Hart makes it easy for novices to feel like they are creating something beautiful. She is really talented in her designs and I have been collecting her patterns for a while now.
I made several sets of coasters with a mix of various fabrics in the hope that adding color to the lives of my loved ones will be well received:) I like making coasters as gifts because everyone needs them but we don't neccessarily buy them for ourselves. After you unwrap them, you don't even need to 'put them away', you just toss them on the table!
