Primitive home decor is what you will find here.&nbsp; It takes you back to simpler times and gives your home a warm welcoming feeling. Primitives caught my eye many years ago. I love the fact that they do not have that store look. Everything comes out different each time they are made. I personally do not like all of the bright decorations, especially for Halloween.&nbsp; I love making primitives with that old grungy effect even though it is sometimes a messy process. I sometimes use patterns from some very creative artists, and sometimes I happen to come up with an idea on my own.&nbsp; Crafting of all kinds is a passion of mine. Primitives are my go-to craft now, but I have made quilts, knitted, crocheted, rug hooking, Punch needle and more. Too many ideas, and so little time to do them all.&nbsp;</p> <p>&nbsp;Handmade is always a great gift. Support the artists here on Goimagine, we put our heart and soul into everything we make. So many special items for the special people in your life.&nbsp;</p> <p>Thank you for stopping by and seeing what I have to offer.&nbsp;&nbsp;</p> <p>If you have any questions about my items please message me.&nbsp;</p> oauth.AntwgwhrZcTXIsWB17wqprfZ59RBy62Tf-f6RPFu._Bu40pVtU2jALTCjlhRfIRtRSCGiaaKx4u6V6j5JRBM UA-257780928-1 A N 1682185108 0 0 0 0 S 276562 GI-276562-RBE P 0.00 1 1.000 0 0 0 0.00 0 0 Y N N B N R N N N Y 10 0 N 0 0 0 0 N 0 P F a:5:{s:16:"min_items_in_box";i:0;s:16:"max_items_in_box";i:0;s:10:"box_length";i:0;s:9:"box_width";i:0;s:10:"box_height";i:0;} 1.000 0.000 2147483647
