A clamping device and method for a conventional sewing or embroidery machine has a pair of movable arms. Each of the arms includes a fixed section and a movable section for receiving material or item to be embroidered therebetween. A manual lever allows the movable arm to be raised for insertion of the material and a scale on the arm allows the depth of insertion to be easily determined for accurate insertion. Each arm is movable along a slotted mounting plate affixed to the sewing machine proximate the sewing head. The clamping device provides uniform, taut material for accurate, smooth embroidering.

I claim: 1. A sewing machine clamping device comprising: a first arm, a second arm, said first arm comprising a fixed section and a movable section, said movable section movable to clamp material between said fixed and said movable sections, a blade, said blade affixed to said movable section to angularly contract the material and force it outwardly to tighten the material between said first arm and said section arm. 2. The clamping device of claim 1 wherein said second arm comprises a movable section and a fixed section. 3. The clamping device of claim 1 said blade is resilient. 4. The clamping device of claim 3 wherein said blade is flexible. 5. The clamping device of claim 1 wherein said movable section comprises a cam, a lever, said lever attached to said cam, said cam engaging said movable section for directing said movable section. 6. The clamping device of claim 1 further comprising a mounting plate, said mounting plate defining a slot, a bracket, said bracket attached to said first arm to adjustably affix said first arm to said mounting plate. 7. The clamping device of claim 6 wherein said bracket defines an aperture, a threaded member, said threaded member positioned in said aperture and in said slot for securing said first arm at a desired location on said mounting plate. 8. The clamping device of claim 7 further comprising a knob, said knob threadably affixed on said threaded member. 9. A clamping device for a sewing machine comprising: a first arm, a second arm, said first and said second arms spatially attached to a sewing machine, each of said first and said second arms comprising a fixed section and a movable section, said movable sections movable to clamp material between said fixed and said movable sections, a pair of handles, a pair of cams, each of said pair of handles attached to different ones of said pair of cams, each of said pair of cams engaging different ones of said movable sections for directing said movable sections. 10. The clamping device of claim 9 wherein each of said movable sections comprises a blade, said blade formed from a flexible material. 11. A method of clamping materials for sewing utilizing a sewing machine and a clamping device having a pair of arms, each of said arms having a movable section and a fixed section, the movable sections each including a resilient blade angularly disposed to the fixed section, the method comprising the steps of: a) spacing the arms a selection distance; b) placing material between the arms; c) adjusting the movable sections to clamp the material between the blades and the fixed sections; and d) allowing the blades to tighten the material between the arms. 12. The method of claim 11 further comprising the step of sewing the clamped material. 13. The method of claim 11 wherein placing the material between the arms comprises the step of manually placing the material in each of the arms. 14. The method of claim 11 wherein spacing the arms comprises the step of moving one of said arms relative to the other arm along the sewing machine. 15. The method of claim 11 wherein moving the arms comprises the step of moving one section of one arm manually.
