Ok Hubs came along & asked me what I was waiting for (me trying to figure out the perfect placement making paper template all that work) he grabbed my piece that I cut out & folded it in half twice & said there's your center piece put the biggest hoop in the middle right there so I did & it stitched perfectly smartie pants! I have to say I held my breath I was nervous it would pop out of the hoop but it was really fine I did slow my machine down too & this is a ripple design that I enlarged quite a bit. the first picture shows the underside where this will go & you can see if has to be a straight edge @ the bottom & the velcro on either side to hold it in place works perfect to. I didn't take a picture of it on the tire since it was too dark to get a good shot with my cell phone but it fits perfectly & hubs is really pleased with it. The heat will take the ripple out of the cover so not worried about the wee pucker @ all. A big thank you to all who tried to give me good advice. I think the next one will have our last name on it if I can do it in a stitch that is like a ripple too.....otherwise it might be too dense to do our name?
