This is how I made the top of the spoolholder for the Carolyn Pearce Home Sweet Home Workbox, from her book. I cut a piece of plastic, and a piece of interlining, with a hole cut in the centre of each.
Then I cut another piece of thicker interlining, with a slightly larger diameter, which went just a bit over the edge of the plastic.
The top of the spoolholder has an eyelet stitched in the centre, for the thread from the spool to emerge, so as I attached the fabric to the sandwich of plastic and interlining, I had to make sure that the eyelet matched up with the hole behind it. I made running stitches around the edge of the embroidered piece with quilting thread, and gathered it up tightly over the plastic, padded side against the reverse of the embroidery.
Then I laced across the back of the fabric to hold the seam allowance down, making sure that I avoided the eyelet area.
I did the same process on a piece of the lining fabric, having stitched an eyelet in the centre first. Then I slip stitched the two circles together, back to back.
To attach the round top to the embroidered wall piece, I placed pins in the very edge of the circular top – placing them at the quarter points first, then adding more pins equally until the top was securely held. This was quite tricky, as the top kept twisting sideways!
Then I slip stitched the top to the tube, removing the pins as I did so.
Using a thread of a similar colour to the fabric, this was a very neat join, which will later be covered with Knotted Pearl Stitch.
I finished this part late in the evening, so this photo is rubbish, but it is supposed to show the lining of the spoolholder at this point!
All I need to do next is to attach the base, and it will be finished.
